MusicForDriving recommends this documentary. Went to see it on last years CPH DOX. Actually we went there by accident. We had tickets for Michael Jackson This Is It, but the people walking into another room looked much more interesting, so we took a chance which played well out. Here is a short describtion:

Presented by Future Cinema in association with Warp Films, directed by All Tomorrow’s People and Jonathan Caouette. This film documents the history of the long running All Tomorrow’s Parties Music Festival, which is often described as a “post-punk DIY bricolage.” The film was created by both fans and musicians who attended the festivals, with Super8, camcorders and even mobile phones. There are some great performances from Grizzly Bear, Sonic Youth, Battles, Belle and Sebastian, Yeah Yeah Yeahs, Les Savy Fav, Fuck Buttons, Iggy Pop, and the list goes on and on.

History

The festival has its origins in the Bowlie Weekender, curated by Belle & Sebastian at Camber Sands in April 1999. Artists, usually musicians (but sometimes visual artists like Matt Groening, whose line-up featured in the Observer’s list of the ten best festivals of the year, or Jake and Dinos Chapman) are asked to curate the festival by inviting their favourite performers to play. The idea is that it is akin to dipping into the curator’s record collection, or as founder Barry Hogan described it, “ATP is like an excellent mix tape”.
In 2002, the festival expanded to the USA, and several events have taken place there in subsequent years. In recent years the All Tomorrow’s Parties organisation has also been involved in booking stages at the Pitchfork Music Festival and the Primavera Sound Festival in Barcelona, Spain. In 2008, All Tomorrow’s Parties ran their first East Coast USA festival, which took place at Kutsher’s Hotel and Country Club, Monticello, New York and was a huge success – this event occurred again in 2009 and 2010. In January 2009, the festival took place for the first time in Australia, with events in Brisbane, Sydney and Mount Buller (in Victoria) all curated by Nick Cave & The Bad Seeds.
The small organisation that puts on these festivals also promote concerts in London and the rest of the United Kingdom, curate the yearly Don’t Look Back concert series and run the record label ATP Recordings.
In 2009, Warp Films released a long awaited feature length documentary about the festival named All Tomorrow’s Parties. It premiered at the SXSW Film Festival, and then premiered in the UK at Edinburgh in June. In October 2009 the film was be screened at a number of ‘one night only’ UK theatrical screenings also featuring live music, with the main act performing to be Les Savy Fav, who feature in the film and have long been mainstays of All Tomorrow’s Parties line-ups.
