On September 6th, a group of artists gathered in L.A. to celebrate the 15th anniversary of Warped Tour, everyone’s favorite annual experiment in the conflicting relationship between black hoodies and hot asphalt parking lots. Warped vets including blink-182, the Aggrolites, Bad Religion, Ice-T, Katy Perry, NOFX, and Rise Against played a show that both raised money for Musicares and feted the enduring tour, known for its uncompromising conditions, rider-free artist living, and confirmed status as a fertile breeding ground for all things trending in rock/emo/punk. The whole thing was filmed for a one-night-only theatrical release this Thursday, September 17th, at movie theaters around the country — but Music Mix readers can get a preview right now. Check out the All-American Rejects doing “Swing, Swing,” and then let us know in the comments: Will you be heading to the multiplex to see the whole film? Hey, it’s the closest Warped Tour will ever come to being air-conditioned…
