The inaugural Outside Lands Festival in Golden Gate Park on August 22-24 looks to make one hell of a splash in the festival circuit with Radiohead, Tom Petty, and Jack Johnson confirmed to headline the event. Festival organizers expect 160,000 people to attend this three day festival, which will tout environmentally conscious living, and will most definitely place San Francisco on the festival map.

The event, which is one week before Burning Man and two weeks before the Treasure Island Music Festival, will be in Golden Gate Park (formerly known as Outside Lands) on four stages spread around the park. The festival gates will be opening at 11 AM every day, with music starting at 11:30 or 12 and ending at 10:00 PM. Tickets and prices haven't been released yet.

Another Planet Entertainment, one of the promotions companies behind the Outside Lands Festival, just recently confirmed the headliners and are promising a full line up soon. Stay tuned to MetroWize for updates and other festival info or check out them out at www.sfoutsidelands.com.
