Blag Dahlia, Rex Everything, Hunter Down, the Fresh Prince of Darkness and HeWhoCannotBeNamed (who tends to perform wearing nothing but a Rey Mysterio wrestling mask) are the maniacs behind the Dwarves, whose on-stage antics and lyrics have led to its music being characterized as “scum punk.” Anything from a re-enactment of Jesus’ crucifixion to on-stage fist fights could ensue. The nudity will continue when the Murder Junkies take the stage — though only drummer Dino Sex plays in his birthday suit. Don’t expect politeness from either group. Detroit-based punk four-piece Busby Death Chair (named for a cursed chair) and local scum punks Grizzled Yinzzers will get the madness started at Cattivo. -Alex McCann
