This tune for Paquachuck Orchestra features some noodling around with the JABB bass clarinet in an unusual context (viola, cello, bass, muted banjo, piano, cymbal, triangle, 2 gongs, 2 drums). It's intended as a brief character sketch.
A sort of jawbone tremolo manifests once in a while in the clarinet--am not certain where it's coming from--haven't had time to explore it in detail. I get a kick out of the low register on this instrument. It gives pretty good honk.
