In conjunction with the upcoming Michael Cera film, Scott Pilgrim Vs. The World (which hits theaters on August 13th), SonicBids and Universal Pictures are sponsoring a  Battle of the Bands: Indie Rock vs. The World; a contest where bands will battle “for their honor and love of music.”

The winning band will get a trip to California and the opportunity to perform live at a Scott Pilgrim-themed event this summer, and have their video included as a special feature on the DVD release of Scott Pilgrim vs. the World. Top 8 finalists will also receive an Mbox® 2 Pro Factory recording package from Avid, valued at $89.! Band submission deadline is May 3, 2010.
