King David's Chanukah Wish List
Back
in the dim, dusty days when I worked in the music department in
Borders, I talked with a customer who was especially fond of harp
music. “I love the harp more than King David!” he announced,
happily. I was able to hook him up with several harp albums that
day, but I wish we had stocked albums by Michael Levy. That customer
would have gone into the stratosphere if he could have heard
Michael's music.
Now
you can hear it for free! Click the links! Write reviews! Get
cracking!!!
A MASSIVE Christmas Present For All My Fans!
A MASSIVE CHRISTMAS PRESENT FOR ALL MY LYRE MUSIC FANS!!! For a limited time, absolutely EVERY one of my 23 releases since 2008 is available for FREE (or as much as anyone thinks my music is worth!) from Bandcamp! If the "free" option is selected, all I would kindly ask in return, is to post a review of the album or single on either iTunes or Amazon..and to spread the word about my little-known lyre music to the rest of the unsuspecting world...
Here is the link to my Bandcamp Page:
Seasons Greetings, Everyone!

Officer Bernadette Kicks Butt
I
enjoyed Anne Hillerman's new book, Spider Woman's Daughter,
set in her late father's Navajo Detective series. I confess, once I
realized she was a writer who had published a book about her father's
journies in Navajoland (Tony Hillerman's Landscape),
I was hoping she might pick up the reins and write a book in his
series. When Spider Woman's Daughter
was released, I snatched it up and dove into it. I quickly
discovered that Anne Hillerman has her father's knack for building
suspense and character. Even more important, she knows how to allow
the reader to work on the mystery along with the main characters. I
loved being able to learn more about the characters of Officer
Bernadette Manuelito and her mother, as well.
Not
to sound like a Philistine, but I did not discover Tony Hillerman's
detective series until two years ago, after I began to work at the
Heard Museum's book store. My mother was devoted to the series for
many years, waiting for each new book with bated breath, so I knew
they wouldn't disappoint me once I picked them up. And yet I still
didn't read them – not until I read Talking Mysteries
byTony
Hillerman and Ernie Bulow (Ernie Bulow also wrote Navajo
Taboos). This slim volume
contains an introduction by Ernie Bulow, a quick autobiography by
Tony Hillerman, an interview in which Bulow and Hillerman discuss
writing and writing methods, and a masterpiece of a short story by
Hillerman. Be sure and turn all the way to the end of the book,
where you'll find gorgeous illustrations by Ernest Franklin depicting
Joe Leaphorn and Jim Chee on the trail of a mystery. Once I had seen
those illustrations, I knew I had to start reading about the
characters.
I
have now read all but the last two books in Tony Hillerman's series,
and I've been very spoiled by being able to pick them up without
having to wait for them to be written. Alas, I'll be forced to wait
with everyone else for Anne's new books in the series.
So
– how much did I enjoy her book? So much, I'm looking forward to
reading the next one. Considering the big shoes Anne had to step
into, this is high praise. But one word of warning: things get hairy
really quick. You'll be on the hook until the very end!
I decided not to try to use any of the cover graphics for these books from google - they would only be taken down, because they're proprietary. The photo at the top of this post was taken in Petrified Forest/Painted Desert national park, which is also Navajo Country.

Yodeling Goats Drive Big Box Bookstore Into Bankruptcy
Years ago, my friend Eileen Rowan and I worked together at the same Borders, and somehow we got onto the topic of the yodeling goatherd song from The Sound of Music. We noodled together a goofy poem about yodeling goats. We didn't finish it, and I stuck it into a file and forgot it.
Then
recently I was putting together a little display at the Heard Museum
book store for a classic kid's book titled, The Goat in the
Rug. I thought of our poem and
dug it up. It only needed a couple of lines to be complete. So here
it is, the yodeling goat song, written by two miscreants on a slow
night at Borders:
The Yodeling Goat Song
This
is the song of the yodeling goats
They
never eat books but they eat lots of oats
They
live in a castle surrounded by moats
Those
dawdling, oat-eating, yodeling goats.
Sing
yodely-ohdely-dohdely-doo
If
you think they’re funny, then I think so too
Sing
Yodely-ohdely-dohdely-day
They
moved in last week and it looks like they’ll stay
The
yodeling goats, the yodeling goats
They
like to eat fish, so they have shiny coats
They
read magazines and sport colorful totes
Those
oft-toting, fish-eating, yodeling goats
Sing
yodely-ohdely-dohdely-dorm
Don't
buy them a jacket, 'cause they're always warm
Sing
yodely-ohdely-dohdely-day
They
ring all the doorbells and then run away
The
yodeling goats, the yodeling goats
They
don’t give a fig for the DOs and the DON’Ts
They don't cross their Ts and they don't mark their quotes
Those
fig-tossing, mis-quoting yodeling goats
Sing
yodely-ohdely-dohdely, please
Let's
run in the meadows and climb all the trees!
Sing
yodely-ohdely-dohdely-dug
There's
a goat in the pen and a goat in the rug
The
yodeling goats, they have golden throats
And
sing acapella, they know all the notes
They
tap dance all summer, then drink root beer floats
Those
tippy-tap, rooty-beer, golden throat goats
Sing
yodley-ohdely-dohdely-dend
This
yodeling goat song, will it never end?
Sing
yodely-ohdely-dohdely-dain

Big Business Is Doo-Doo (And Not In a Good, Fertilize-the-Crops Kinda Way)
I've
heard it since the 1960s, and some of you may have heard it since the
1930s: Big Business is no friend to the worker. This is a Commie
attitude, but it's also true – it can't be denied. The goal of any
big business is to hire as few people as possible to do as much work
as possible for as little money as possible. If the Big Business
model is to be realized in its purest form, there should also be no
benefits to go along with any job, other than the privilege of having
it in the first place: no sick days, no insurance, no overtime, no
paid holidays or vacation (in fact, no time off at all), no breaks,
no limits to the hours worked daily, and no compensation for injuries
received on the job. After all, if you work hard enough for your
pittance, the quality of your character and your own native
intelligence should shine forth and cause you to advance in the ranks
until you become prosperous, right? After all nepotism, cronyism,
and pure greed never factor into the equation at all.
But
that's old news. All of that has been said before, and much better,
by others. I've got my own argument for why Big Business is doo-doo.
It comes from an experience I had at Borders, the big book chain
that bit the bullet back in 2011. Prior to the sinking of that ship,
we were engaged in rearranging the deck chairs, and at that point the
doo-doo had become so thick, we were slipping and falling into it.
Things
had become particularly nasty in 2008-2009. A new CEO had been
hired, and though he resembled Mister Rodgers, he was actually the
malignant doppleganger of that guy. He decided that we had to become
relevant to our venders (the publishers who provided us with our
product) by turning selected titles into bestsellers. (Personally, I
think we would have become more relevant to them by paying them what
we owed them, but that's just me.) The best way to do that,
according to him, was to recommend these titles to absolutely
everyone who came through the front door, regardless of what they
were looking for.
So
we all had to sit through training films on the computers in the back
office to prove we could sell these select titles to people. In the
films, a Borders employee would pose as a customer and ask the
other Borders employee (posing as herself) for a book. Invariably, the
sort of book they wanted was exactly the sort of thing we were
promoting that month. We all electronically signed our initials at
the end of these programs to indicate that were were enlightened as
to the technique of selling books people didn't want and hadn't asked
for.
One
month, our selected title was in the Zombie Classics series. I don't
recall the exact title, but for the sake of argument let's call it
Jane Zombie. So, here I am
at the information desk, answering phones and desperately trying to
think up ways to insert the subject of zombies into the conversation
without sounding like a nut case. A guy walks up and asks, “Do you
carry the Chilton manuals for car repair?”
In
the old days, I would have said Yes
and walked him back to the car repair section, then helped him find
the title he needed. Under the new regime I was obliged to say, “Yes
sir, it's called Jane Zombie.
It's the story of an undead governess who eats brains and repairs
cars.”
Okay,
I didn't actually say that, but I was sorely tempted.
That
CEO eventually utilized his golden parachute and quit the company,
moving on to another field where his techniques at mental torture
might actually advance national security (or so I imagine). His
methods for saving Borders from destruction did not work
(because, as I mentioned earlier, they did not include the method of paying our bills). Borders went down, and a good many
people drowned or died of hypothermia. Another Big Business success
story (at least for the executives who managed to squeeze fat
“retention bonuses” out of the dying carcass).
I'm
not trying to say none of that crap goes on at the small/medium
business level. There are plenty of self-made men and women out
there who will bite your head off if you ask for any time off, who
can't afford to offer insurance, or who may fire you because you're
good-looking and that may threaten their marriage (or hire you for
the same reason).
But
the funny thing about good workers is that they really are hard to
come by. Smaller businesses tend to have bosses who interact with
the workers and who are involved in daily operations on the ground
level. They notice who is competent, and reliable, and honest. Big
businesses are managed from an extreme distance, they don't know or
care who works for them unless the margin moves perceptibly, which it
may do for any number of reasons. If there are hundreds of small
businesses operating in a given town, you have choices where to work.
If there's only one, and it's Walmart – god help you.
Here,
let me recommend a book that may help you with your plight. It's
about a zombie governess who eats brains and earns extra income
through stock investments.
Once again, I have plundered Ernest Hogan's stock of wacky illustrations, which somehow always seem to fit the tone of these posts. I have probably used some of them before, but that's just a bunch of tough noogies.

Mucho Mega Music from Michael
Michael
Levy has some wonderful news about his re-re-release, and some
fabulous links for you to follow. Check out every single one of them,
and don't forget to write reviews!
Third Time Lucky!
I am pleased to announce the re-re-RE release of my second compilation album, "Musical Adventures in Time Travel"...phew!
Trying to compile a suitable selection of the best tracks from my lyre albums has proved to be a task which almost needed the invocation of Apollo to achieve. It all began earlier this year...
At 23 tracks, the first release was far too long to fit onto the physical CD of the album (manufactured on demand by Reverbnation) and I grew to hate the album artwork I somewhat too hastily came up with!
In the second release, I loved the album cover - "Alcaeus of Mytilene playing a kithara while Sappho listens" by Lawrence Alma-Tadema, 1881".Tadema does through art, what I intend to do through my music! However, at 22 tracks, I still could not squeeze them all into CD format, and since its release, I had recorded my new extended length single, "Orpheus's Lyre: Lament For Solo Lyre in the Just Intonation of Antiquity" and my audio producer, Dominik Johnson also came up with an amazing new mix for my other extended length single, "Ancient Lyre Strings", both of which I wanted to include in the final compilation...ARGH!
Therefore, in the third and final release, I edited the compilation to my favourite18 tracks. These include the track "Realm of the Ancestors" - for possibly the first time in 3000 years, a unique duet of lyre and harp, featuring the wonderfully delicate harp accompaniment to my spontaneous lyre improvisation, provided by the talented folk harpist, Rebecca Penkett
In my endless quest of seeking musical perfection, my final version of "Musical Adventures in Time Travel", now includes all my extended length singles, including a track which only exists by pure serene serendipity...
"The Battle of Thermopylae - Paean For Solo lyre", another of my recently released extended length singles, was originally nothing but a random rough recording I did whilst improvising in my experiments to try and imitate an electric guitar pitch-bending "whammy bar" on lyre - using my right hand wrist as the said "whammy bar" on the top string above the bridge, during some wild strummed sections!
I uploaded the raw audio file to Mediafire for possible future use and then completely forgot about it - for 3 years!! It was only whilst I was providing Dominik Johnson with the Mediafire URLs of my raw audio files for mixing in compiling "Musical Adventures in Time Travel", that purely by chance, I happened to accidentally copy and paste the URL to my frenzied lyre whammy bar improvisation, instead of the track I actually intended to send Dominik to mix!
The result is a bit rough and hissy compared to the other tracks in the compilation, but it sure ROCKS!!! Here is a video I recently uploaded to my Youtube Channel, featuring a clip of this piece:
The Rocky Road To Musical Perfection!
My second compilation also demonstrates the ruthless, relentless refining process I have put myself though over the last few years! My arrangement for solo lyre, of Dr Richard Dumbrill's interpretation of the 3400 year old Hurrian Hymn Text H6, started out as a now virtually viral, lo-fi Youtube video (recorded back in 2008 with my then suitably "Bronze Age" webcam!):
I eventually recorded a better quality version of this arrangement, which I bravely attempted to mix myself on my chunky old desktop, which then featured in my early experimental album from 2009, "An Ancient Lyre" - the only album I have ever been bold enough to attempt to produce from scratch myself!
Later in 2009, thanks to the now sadly defunct Myspace, I became acquainted with the awesome music production skills of Dominik Johnson, who masterfully re-mixed the raw audio of the recording - this then featured as track 1 from my first compilation album of 2011, "Ancient Landscapes".
In my new version of the Hurrian Hymn, now forming track 1 of "Musical Adventures in Time Travel", this time, I recorded my arrangement on my new hand-made lyre, using strings made of wound silk (made by ancient string technology expert, Peter Pringle) for a unique, truly ancient timbre - these strings provide almost the nearest match in tone to the unpolished strings of either wound gut or natural fibre which were generally used on the actual lyres of antiquity.
In this new arrangement, I also tuned my lyre in the wonderfully pure-sounding just intonation of antiquity, and for the repeat of the theme in my new arrangement, I experimented in the ancient Mesopotamian percussive lyre playing technique (using a small wooden baton to hit the strings, rather like a hammered dulcimer).
In the production of this track, Dominik also somehow managed to create a haunting natural reverb, authentically sampled from an actual Iranian cave -the relentless quest of seeking musical perfection!
This final arrangement of the Hurrian Hymn is currently being used in support of the exhibition at the Royal Ontario Museum - "Mesopotamia - Inventing Our World" (CDs of "Musical Adventures in Time Travel" are also available to purchase from the Royal Ontario Museum Shop). Below is a video featuring a clip from my new arrangement of the Hurrian Hymn:
The physical CDs of my compilation album "Musical Adventures in Time Travel" and indeed, of absolutely every other one of my many releases, are available to order, anywhere in the world, from my Reverbnation Store. This epic new compilation album is currently available from iTunes, Amazon, and lossless audio or 320kbps quality MP3s of the album are available to download from both CD Baby and Bandcamp.
NB! Any new reviews of either this new album or any other of my releases on either iTunes or Amazon would be utterly, amazingly appreciated - many thanks!!

Maybe It Takes More Oomph
We
have some interesting examples of continental rifts in the world, as
well as spreading ridges in oceanic crust – and since these are
both examples of diverging boundaries, geologists are justified in
assuming that similar processes are involved in rifting. But that's
a hypothesis. Observations of the process of rifting in the real
world are revealing that continental rifts are more complicated.
One
reason may be that oceanic crust is denser, but thinner than
continental crust. The difference between them is demonstrated when
the two types of crust are driven together. Continental crust is fat
and buoyant, so the immense pressure pushes the thinner, denser
oceanic crust beneath the continental crust (subduction). Water
vapor that subducts with the oceanic crust allows it to melt at lower
temperatures than it normally would, and the partially melted stuff rises through the continental crust above the subducting slab.
As it rises, the reduced pressure allows it to melt further, where it
also melts some of the surrounding continental rocks. It may pool
between sedimentary layers, forming plutons, sills, and dikes that
cool underground, or it may extrude onto the surface and form
volcanoes. That's what can happen at a converging zone. But at the
other end of that zone is a rift.
Oceanic
rifts are ongoing projects – upwelling convection currents in the
mantle inflate and stretch the crust above, causing fractures.
Magma squeezes through fractures, forcing the crust apart even
further, and forming spreading ridges. You might think that the
magma would cool and plug the holes – something that happens quite
often when magma extrudes onto continents. But the plug is temporary. The centers of those new dikes are weak, and they fracture from the pressure of the uprising heat, allowing more low-silica magma to flow into the new fracture.
Silica
is sticky stuff. Magma with a higher silica content is less runny.
At oceanic rifts, the runny, lower-silica magma is a lot less likely
to clog up the dikes and vents through which it is welling. That
low-silica magma actually cools at higher temperatures, and water is
present to speed that cooling. But when magma cools, it shrinks, and
fresh hot stuff can well up around it, gradually forcing the rift
zone apart. You can actually observe the whole,
extrude-shrink-extrude-again process in the nifty pillow lavas that
form around oceanic volcanoes as magma hits the water, instantly cooling
to form a shell, which bursts at its weakest point and forms a new
blob when more molten rock is forced into it. (If there was a cable
channel just for watching pillow lavas form, I would sign up for it.)
Oceanic
rift zones seem to last as long as the upwelling convection currents
that drive them (a phenomenon called slab pull
may also be involved, with the weight of the dense continental crust
being subducted into the mantle possibly pulling the plate from the
other end). But continental rift zones may require more oomph to
keep them going.
This
oomph could be a mantle plume (as is the case with the caldera below
Yellowstone), or an upward convection current combined
with a mantle plume (as is the case with the rift zone in Iceland.)
But Yellowstone is considered a supervolcano rather than a rift zone,
and Iceland is a comparatively small chunk of continental rock.
There's a continental rift under way in Colorado and New Mexico, but
it's pretty low key when compared with the poster child of
continental rifts, The African Rift.
Theoretically,
the African Rift is doing the same thing that the Arabian Gulf is
doing, forming a basin as the crust spreads apart that will
eventually open up to form a new sea. The Atlantic Ocean formed that
way when Pangea broke apart. Since spreading ridges in oceans are
faulted all the way down to the mantle, you could expect that a
continental rift would also have faults that run that deep. Evidence
for that can be found in low-silica volcanic rocks in the Southwest
U.S. Arizona even has a shield volcano, the sort of volcano one
would usually expect to find above a mantle plume forming an island
chain (like Hawaii). Yet the volcanoes along the U.S. Rift are not
all of this type. Likewise, the volcanoes that have formed along the
sides of the rift zone in Africa are a grab bag of different types,
anything from volcanic vents and relatively flat volcanoes, to giant
composites like Kilimanjaro.
What
this suggests is that sometimes low-silica magma is reaching the
surface along these rifts (often creating extensive sills and dikes
along the way), and sometimes it's mixing with the continental rocks
it encounters on its upward journey and melting that stuff,
introducing more silica into the mix and building composite cones at
the surface, or cinder cones, or volcanic domes, or even creating
plutons that cool underground.
Besides
the silica ratio, another thing that determines the size, shape, and
explosiveness of volcanic features is the amount of volatiles in the
mix – gases. High silica/low gas mixes produce volcanic domes that
extrude almost like toothpaste. Low silica/high gas mixes produce
cinder cones. An intermediate mix can produce a composite volcano,
like the one above Flagstaff, Arizona (far inland from where you
would expect to find such a structure). The super-volcanoes of the
Western U.S., Yellowstone and the Valles Caldera, are very
high-silica caldera volcanoes that fractured the crust overlying them
with expansion caused by heat, which allowed gases to escape through
the cracks, widening them further and causing a collapse.
The collapse of that surface material into the caldera produced titanic explosions. The rhyolitic tuff (fused ash) of
Bandelier National Monument in New Mexico was created by an explosion
from the Valles Caldera. Compare all that complicated stuff to good
ol'oceanic rifting, and it just seems like such a straight-forward
process in comparison.
Continental
rifts seem like a lot more work. Maybe that's why continental rifts
sometimes seem to just stop. The rifting had some oomph when it
started out, but the upwelling current shifted, or the plume stopped,
or the older part of the craton, where the crust is too thick to be
rifted, moved over the whole bubbling mess. (The tectonic plates,
including continents, move gradually but steadily over the upper
mantle.)
One
failed rift is the North American Mid-Continental Rift (extending
from Lake Superior to Oklahoma), which seems to have pooped out about
a billion years ago. At that time, we were part of the
supercontinent Rodinia, which split up about 750 million years ago.
Two other supercontinents formed and broke apart after that.
Eventually, North America will collide with Asia, and the rifting
will start somewhere else.
But
regardless of what happens in the future, the African Rift is
happening right now, in some ways that were predicted, and in some
ways that were not. It will continue to be a fascinating example of
what happens when continents are pulled apart.

Did the Romans Invent the "Whammy Bar"?
New blog just posted on my website, about a fascinating potential new musical discovery from a detailed painting of a Roman Kithara found in Herculaneum, which seems to amazingly show the 1st century CE equilvalent of a pitch-bending "whammy bar!"

Let's Just Suck That Pesky Carbon Out Of The Air With Our Giant Vacuum Thingee
There
has been a lot of talk (and study) recently about the concept of
carbon sequestration, the idea that CO2 gas could be pulled from the
atmosphere and stored in sedimentary layers underground, or even
under the seafloor. Some very smart geologists are working on this
problem, and we may see an attempt to implement the idea within the
next few decades. But I'm always curious when I hear about these
sorts of projects, because I wonder just how much non-geologists
understand about faults and fractures in the Earth's crust, even the
non-geologists who have a financial stake in what their geology
experts tell them.
Okay,
maybe especially these guys, since money folk and bureaucrats tend to
be people who think in terms of deadlines and progress reports: this
phase of the project was completed on schedule, this other
phase is over schedule, the cost breakdown is this, etc.
They're thinking weeks ahead, sometimes decades ahead for some
aspects of a project. But geology is often reckoned in millions,
even billions of years. What's even trickier is that, despite
this immense time scale, geology can also change suddenly and
catastrophically, in a matter of seconds. Thirty feet of sediment
can be deposited by a flash flood, tons of volcanic ash can hurtle
toward a town at 100km an hour. And in the case of carbon
sequestration, the problem is that faults move.
CO2
is heavier than the mix of gases that make up our atmosphere. If a
large amount of it is suddenly released, it will flow and pool almost
like water at ground level. It is invisible and odorless, so it
overtakes unsuspecting people and animals and suffocates them before
they realize that anything is wrong. Eventually it will mix with the
other gases and be reabsorbed into the atmosphere, but not before
killing every oxygen-breathing creature in its path. Villages next to lakes that have formed near the continental rift in Africa have
suffered from accidents like this from gases generated by volcanic activity under the lakes,
releasing the CO2.
So when geologists are trying to advise people about where
sequestered CO2 could safely be stored, they have this
possibility in mind.
Yet
the geologists can only advise, very few of them are in a position to
make the final decisions about whether a project will go forward and
where it will happen. And when it comes to faults, we're mostly
engaged in guesswork. This became very plain to me when I recently
toured Kartchner Caverns, in Southern Arizona, with the head
geologist for the State Park Service. He said that they could see
where a few of the faults in the landscape were by looking at the
mountains and valleys on the surface. But once they went
underground, they found many more faults and fractures that could
never have been seen without the benefit of a cave system.
Improved
seismic monitoring has proved that the Earth's crust is constantly
moving, shrinking, expanding, fracturing, dissolving, collapsing, and
getting pulverized, thanks to the titanic pressures of the
surrounding rock and the heat generated in the mantle. What appears
to be motionless to us on the surface is actually dynamic.
So
theoretically, tons of CO2 could be stored somewhere, a fault could
move, and gas could escape and suffocate people and animals. So they
have to find a place that seems relatively stable, but they also have
to find one that isn't too close to human habitation, because no
place on the Earth's surface is 100% guaranteed to be stable.
Storing the gas in the ocean floor, where the immense pressure of the
ocean will keep it dissolved in those sediments, is a safer bet, but
then you have the added cost and difficulty of getting it down there.
So
where will the gas end up? If they get to be too good at pulling the
CO2 out of the atmosphere, will people say, Whoopie! We can
generate as much CO2 as we want!
Will it trick us into keeping old technologies that are causing
problems?
If
the sequestration process works, it may have an interesting side effect – it
may cause calcite to form when moisture enters the soil. In Arizona,
moisture reacts with CO2 in the soil to form CaCO3. Who knows, maybe
a whole new generation of caves will sport formations resulting from reactions with the CO2 we
placed in overlying beds.
