Last summer, those who attended the first annual Outside Lands music festival in Golden Gate Park were treated to many "only in San Francisco" moments. There was the night Radiohead performed dreamy postrock symphonies, shrouded in fog. Or the time indie songwriter Bon Iver got the entire crowd to sing along under a canopy of trees. Or the afternoon when every hour produced not only a different artist lineup (Tom Petty, Lupe Fiasco, Devendra Banhart), but also a completely different weather pattern. You'll never find another concert like Outside Lands, in large part because the gargantuan city park is peerless as venues go. The weekend blowout packs it with local food vendors, hometown art, and crazy amounts of live music. This year Outside Lands goes off August 28-30 with a lineup that includes Tom Jones, the Beastie Boys, TV on the Radio, and the Dirtbombs. This is one event where the location alone keeps interest stoked in repeat performances.
