Steel Pole Bath Tub/ Alice Donut

This is a double bill for people who remember when underground actually meant something. Steel Pole Bath Tub formed in Bozeman, Montana in 1986, relocated to Seattle, then landed in San Francisco where they became fixtures of the Boner Records scene alongside Melvins and Jawbreaker. Their sound—chaotic, noisy, built on TV and movie samples—helped define what noise-rock could be before the majors came sniffing around in the mid-'90s. They opened for Faith No More, got signed to Slash Records, and promptly made an album the label deemed "unlistenable" (they later released it under that title). After years of silence, they've been playing sporadic reunion shows since 2008.Alice Donut brings the NYC counterweight: punk with elements of prog, Zappa-esque weirdness, and enough musical chops to make the chaos feel intentional. They spent a decade on Jello Biafra's Alternative Tentacles, played their 1,000th show in London in 1995, and called it quits—until they didn't. The New Yorker called them a "dadaist punk ensemble," which is about as accurate as anything.GAMH is the right room for this. High ceilings, good sight lines, and a crowd old enough to have been there the first time around. Expect loud, expect weird, expect people who haven't been to a show in years remembering why they used to go to shows.
