Forged in the industrial depths America’s Rust Belt, alt-rockers Pere Ubu dropped their experimental avant-garde rock on Metro on October 4, 1991. By the time of their Chicago stopover, the Cleveland-based alt rockers had made more than just a few trips around the block—they reigned highly over the underground garage rock scene. But Worlds in Collision, the band’s 1991 release, was a huge departure from their comfortable new wave domain, featuring slick guitar riffs and glittery synth breaks. The experimental outfit didn’t arrive without a warm Midwest welcome—locals The Drovers busted out their Irish dance music-influenced tunes while The Coctails showcased the urbanite drone that the Windy City breeds. Take a look at an ad for the show above.
