One of those chain of thought journeys led me to this. The Chapman Stick is a rather unique instrument. I have a soft spot for this particular piece as I got to perform the Toccota (widely known as the Phantom of the Opera song) on an honest-to-goodness pipe organ back in the day.

So folks, enjoy the highbrow moment and a crazy instrument.
