More hardcore experimental-music persons might know Alan Bishop as a member of outer-space-based avant-garde ensemble Sun City Girls, or as cofounder of Seattle label Sublime Frequencies, which has exposed some of the most distinctive musical oddities this side of the Fourth World. With inspirations ranging from psychedelic rock, to free jazz, to found sound, Bishop's set will rivet with extrasensory sonic emissions. Tonight marks the release of Radio Moderna, his new tape (via local cassette label Alterity 101) composed of real-time improvisations for radio. With r millis and Noisepoetnobody. Josephine, 8 pm.
