Kanye West and Smashing Pumpkins will headline the 2007 Bang! Music Festival, to be held Nov. 10-11 at Miami's Bayfront Park Amphitheatre. Tickets go on sale Saturday (Sept. 1).

Thirty acts are expected to perform at the Haddad Productions-steered event, which is expanding to two days this year. Confirmed so far are the Bravery, Riverboat Gamblers, Automatic Loveletter and Kevens.

Bang! debuted in 2005 with a lineup featuring Fischerspooner, VHS Or Beta and the Brazilian Girls. Last year's festival boasted appearances by Daft Punk, Duran Duran, Gnarls Barkley and Modest Mouse.
