Spank Rock, Cabaret Voltaire, Edinburgh, August 30

Spank Rock MC Naeem's stage presence is equal parts Kool Keith, Prince, Schoolly D and Rick James. He's a "badass muthafuckin' cool jerk" in a button-down shirt and Erkle glasses, redefining geek chic. He preened and posed kinetically, spitting out renditions of Backyard Betty and Sweet Talk that sent the crowd into pandaemonium, the usually stoic hip-hop hoodies throwing shapes like disco queens. In between songs, the three man DJ team of Chris Rockswell, Ronnie Darko and xxxChange scratched and cut on two laptops, four decks and a variety of gadgets, applying the logic of the Scratch Perverts to fevered electro, techno, soul, and cuts from their hilarious 'Couche Tard' mixtape. After just two songs, everyone in the crowd was a baying, screaming fan. An encore featuring Naeem rhyming over Gnarls Barkley's Crazy sent the room delirious, as Darko performed an Air Cock Thrust. Naeem passed his vodka bottle around the front rows, and invited the ladies up on stage to dance, his DJs shouting: "We appreciate your vaginas!" Spank Rock have laid down the blueprint for the future of hip-hop, successfully fusing the legacy of acid house and rave culture with intelligent rap. The result is the freshest, most infectious, outrageously sexy live performance you could imagine. [Bram Gieben]
