Tonight's Broken Disco marks the Seattle debut of Berlin's Alex Ridha, aka Boys Noize, a standout among the current swell of hard-rocking techno producers. Boys Noize's debut full-length, Oi Oi Oi, is a relentless electronic beatdown, full of hard- punching drums, thick bass, gnarly synths, and overloaded distortion. It's also an exhausting hour-long dance party. Boys Noize's remixes of Feist, Bloc Party, Tiga, and others demonstrate his skill at the boards and his pop crossover tastes. Incite!, a new alias for Decibel Festival's Sean Horton, opens. (Chop Suey, 1325 E Madison St, 324-8000. 9 pm, $15, 18+.) ERIC GRANDY
