Derek Caterwaul is a longtime promoter of local, underground culture. He’s a DJ on 89.9 KUNM FM’s “Music to Soothe the Savage Beast,” which airs Tuesday nights from 10 p.m. to 1 a.m., and he has ties to the Mystery Media Free(k) box—formerly in the 200-block Cornell/Stanford alley—and now other free art boxes around town. Caterwaul is also responsible for Low Life, a DJ night at Blackbird Buvette (509 Central NW) that contains the sweet sounds of deep psych, garage, roots, post punk and punk, funk, and obscuro. On Thursday, Jan. 26, Low Life celebrates a one-year anniversary. This free, 21-and-over event includes guest DJs, free mixtapes and CDs, and video projections from Billy Da Bunny.
