It’s all about the D’s this week in dance club land: disco, DFA, dress-up, DJ divas and a very big Do-Over. Black Disco and Shits & Giggles got DFA Records in da house once again, this time, serving up the sweet disco-tech treats of Tim Sweeney (Beats in Space). Cosmic craziness on the floor is guaranteed. Club 740, 740 S. Broadway, dwntwn.; Fri., May 15. www.blackdisco.net. Over at Avalon, DJ Skeet Skeet and The Knux provide sounds for Hollywood Prom 09, in which guests don formal wear and bust it like school’s out for Summer. 1737 Vine St., Hlywd; Fri., May 15. www.hollywoodprom2009.com. Hang the DJs offers its 6th annual All-Girl Dance Party with a gaggle of the city’s best turntable temptresses, plus makeovers and mani’s. Echoplex, 1154 Glendale Blvd.; Sat., May 16. www.myspace.com/hangthedjs. If you have any mojo left, the backyard BBQ vibe of The Do-Over returns this Sunday for “Season 5,” and their famous surprise, super-stellar decksmith roster will kick off Summer early with funky party jams and hip-hop classics … and they’ll be doin’ it well.
