Radiohead, Tom Petty and Jack Johnson will headline the next multi-band summer gathering, the Outside Lands Music & Arts Festival. The multi-faceted, three-day festival will take place at San Francisco's Golden Gate Park from August 22-24, 2008, featuring an eclectic mix of rock, blues, reggae, jazz, hip-hop, world, soul, Latin and electronic music on five different stages. The event is organized by Another Planet and Bonnaroo masterminds Superfly and a portion of every ticket sold will directly benefit Golden Gate Park. The world-famous park has hosted a number of mega-events over the years, including Peter Gabriel's WOMAD Festival, the Tibetan Freedom Concert, the Guinness Fleadh Festival and the Love and the Laughter & Music tribute to Bill Graham, as well as performances by Pearl Jam, Neil Young and most recently the Dave Matthews Band.
