How would you like to spend Saturday, August 22 at Pomona Fairplex, rockin' out to the sounds of Linkin Park (in their only North American performance in 2009), Tool, Alice in Chains, Wolfmother and a bunch of other mosh-worthy bands...for free? Metromix Los Angeles is giving away a pair of tickets to Epicenter '09, Southern California's newest and mightiest summer music festival, featuring 12 hours of music on two stages. To quote Linkin Park's Chester Bennington, "If we weren't performing, we'd come just to see all the bands."
