ATP (All Tomorrow's Parties) was a London-based organisation that put on annual music festivals in the UK and in various other places for more than ten years. Festivals tended to be guest-curated by groups (like Sonic Youth, Boards of Canada and Shellac) and typically included experimental music from any genre.

This app uses All Tomorrow's Parties festival lineup data from a custom database, generated from a fan-maintained wiki, to create randomised playlists using the Spotify API.

The app is still undergoing development. Unfortunately, for the music to play from within this application, you'll need Spotify Premium. I'm working on features for non-premium users.
