All Tomorrow's Parties (festival)

All Tomorrow's Parties (ATP) was a UK organisation based in London that promoted music festivals, concerts and records throughout the world for over 10 years. It was founded by Barry Hogan in 2001 in preparation for the first All Tomorrow's Parties Festival, the line-up of which was picked by Mogwai and took place at Pontins, Camber Sands, England.

Named after the song "All Tomorrow's Parties" by the Velvet Underground, the festival exhibited a tendency towards post-rock, indie rock, avant-garde music, and underground hip hop, along with more traditional rock fare presented in smaller venues than typical stadium performances. It was at first a sponsorship-free festival where the organisers and artists stay in the same accommodation as the fans.^[1] It claimed to set itself apart from festivals like Reading or Glastonbury by staying intimate, non-corporate and fan-friendly.^[2] Another difference was the line-ups being chosen by significant bands or artists, resulting in unorthodox events which often combined acts of all sizes, eras, and genres.
