In 1999, cult band Belle and Sebastian staged a festival at a British seaside holiday camp in an attempt to wed the vacation experience with a series of musical performances. The event was a generational Woodstock for indie geeks, and the idea was soon transformed by promoter Barry Hogan into All Tomorrow's Parties, a yearly artist-curated concert series by the sea featuring the titans of contemporary alternative music.

Constructed of footage shot over the course of seven years by over 200 concertgoers and musicians on Super 8, camcorders, and cell phones, this uniquely immersive film captures the sights and sounds of ATP from its inception to recent years, aiming not for a comprehensive document so much as a taste of the festival experience itself. The dizzying array of performances and celebrity sightings includes Sonic Youth, Patti Smith, Iggy and the Stooges, Animal Collective, The Dirty Three, Mogwai, and more, but, it's the odd moments that are most memorable: a Lightning Bolt performance busted by the camp administration; the boys from Grizzly Bear singing on the beach at dusk; a house band formed by drunken revelers.
