Ode To Odd Instruments

I ran across this little ditty on YouTube, played in 5/4 time by Michael Hearst.

The rhythm is kept by a Knockman Cha Cha (which Hearst calls "Chachak").  Various melodies, chords, and accompanying parts are played on the daxophone, Hohner claviola, bass melodica, stylophone, otamatone, and Moog Theremin.  For percusssion, there's an Elasticbrand Audioware rattle and a porter's bell.  The Theremin is named after its Russian inventor.
