(DJs) The Heavy Mental Army primarily spins disco, heavy metal, and rock 'n' roll. He and DJ Fucking in the Streets played Members Only recently and reunite tonight for what they're calling Disco Blood Bath. It will include baile funk—a Brazilian form of hiphop that mixes Portuguese chanting ("I love your big ass, I love your big ass/move your big ass into my crotch, move your big ass into my crotch")—with dirty Miami booty bass. There will be no parking on the dance floor. (Re-bar, 1114 Howell St. 9 pm, $1 with costume, $3 without.) CHARLES MUDEDE
