(GHETTO-TECH) As subtle as a Hustler cartoon, DJ Assault brings full-frontal XXXcess to club music. One of the pioneers of ghetto-tech (a Motor City mashup of Miami bass, electro, and dirty-minded rap), Assault has inspired enough grinding to supply Starbucks with a year's worth of java. The Detroiter's sets typically inspire rump-shakin' mayhem courtesy of such tender classics as "Pop That Ass," "Bend Over," "Big Booty Bitch," and the poignant "Ass-N-Titties." Wear your hottest thong. (Baltic Room, 1207 E Pine St, 625-4444. 9 pm–2 am, $10, 21+.)
