Last month's debut of Broken Disco was a blast. But it was just a taste of what Seattle's electronic scene—represented here by Decibel, Fourthcity, Shameless, and Sensory Effect—can pull off. Tonight, the bass and the BPMs will pump courtesy of booty-breakcore prodigy Knifehandchop and NYC's low-end maestro Passions. With local support from SunTzu Sound in the main room and ndCv and Nordic Soul in the 21-plus "make-out room," this month's installment should be even more off-the-wall fun than last time. (Chop Suey, 1325 E Madison St, 324-8000. 9 pm—4 am, $10/$6 after 2 am, 18+.)
