3Oh!3 This nutty duo, harking from the cool climes of Boulder, Colo., is comprised of Sean Foreman and Nathanial Motte. Using the area code of their hometown as a funky moniker they scrounge and splatter a funky mishmash of electronica, rap and general goofiness. There are scads of hip-hop bravado and self-promotion sprinkled with ballady interplay and toasty beats. Notoriously popular on MySpace and the Warped Tour, the blokes can get old pretty quickly, though. Also on the bill are Innerpartysystem and Chain Gang of 1974. Tremont (Shukla)
