Back in the ’90s there was a thing called rap-rock. Bands like Limp Bizkit, Kid Rock and Papa Roach played a blend of two genres that was energetic, unrestrained and oftimes perplexingly pompous. As the new millennium dawned, those who took the macho mash-up seriously (Beastie Boys, Rage Against the Machine) added a sense of postmodern (there’s that word again) deconstruction to it and survived, while the others drowned in the sweat produced by their own backwards baseball caps. Well, not all of them drowned. Case in point, The Chimpz, a City of Angels outfit who’ll be gigging, bigger than life and better than their sodden predecessors, at Ned’s (2509 San Mateo NE) on Thursday, May 28.
