You can find Beth Fleenor fearlessly indulging her wildest creative inklings whenever she materializes in a musical forum. A classically trained clarinetist and imaginative soloist and with a music degree from Cornish, Fleenor has made a name for herself in Seattle’s experimental-music scene both as a solo artist and with well-known composers like Wayne Horvitz. The music Fleenor makes with Crystal Beth & the Boom Boom Band falls somewhere between the grisly skronk-punk of Stickers and earthy freak-indie of tUnE-yArDs, but even fans of those left-of-center acts will be thrown for a loop. Wailing vocals not bound to any conventions but Fleenor’s own, paired with percussive “Bethnic chants,” are set over freely drawn jazz figures and world-y rhythms. TODD HAMM
