With their stacks of synths, buggy goggles, and black-and-white checkered hoods and pajamas, these two Florida nerds look like yet another gimmicky concept band. Fortunately they don't have a kooky agenda or implausible backstory we're supposed to buy into--they're just here to rock our party and wear goggles while they do it. It'd be easy to pigeonhole their first properly released full-length, In the Reptile House (S.A.F. Records), as an offshoot of new wave, but on a closer listen you can hear all sorts of influences--Lightning Bolt, manic ballpark organ, Jean Michel Jarre's soundtracks from the 70s, Paper Rad--in their dorky robot wiggle. Their sound is a comment on dance music, simultaneously quizzical and mocking as it co-opts and then destroys bits of 80s rave and electro-pop in a dissonant blast of Day-Glo flash. Onstage Yip-Yip uses plenty of strobes and pulsing disco lights, so if you're seizure-prone you might want to consider a welding mask. J+J+J headlines, the Show Is the Rainbow plays third, Yip-Yip goes on second, and Brilliant Pebbles open. a 10 PM, Beat Kitchen, 2100 W. Belmont, 773-281-4444 or 866-468-3401, $10, $8 in advance, 18+.
