(NEW & IMPROVED EXTRAVAGANZA) Seattle's loudest marriage of music, performance, and chaos takes a step toward the big time tonight, by moving to EMP and enlisting as its competitors two punk rock legends: Jello Biafra of Dead Kennedys and Wayne Kramer of MC5. Watch them battle each other for the title by writing songs on the spot while drinking five shots of booze in 45 minutes and getting assaulted by clowns, literal and otherwise. (EMP Sky Church, 325 Fifth Ave N, 770-2777. 8 pm, $10, 21+.) SEAN NELSON
