Live @ ATP is a collection of the songs played during the performance of Boards of Canada at the 2001 All Tomorrow's Parties. Although unofficial and never released by Boards of Canada, they can be found widely on file-sharing networks in their complete form. As with all of their current live work, the collection includes songs that had never before been released and were unnamed.
All Tomorrow's Parties is an annual music festival. The 2001 edition, curated by Tortoise, took place at Camber Sands Holiday Centre, New Lydd Road, Camber Rye, East Sussex from April 6 through April 8. Boards of Canada performed on April 7th.
1: Unreleased as of current date
2: Not yet released at date of performance
Track 1 was revealed as "Echus" when a snippet was featured in the 2009 All Tomorrow's Parties documentary.[1]
Track 3 is essentially the same piece used by Chris Cunningham in the Telecom Italia ad "Quiet", and is often mislabelled as "A Is To B As B Is To C".
Track 6 was used exclusively as a loop on the Boards of Canada webpage circa 2000 and 2001. See the web loops video below.
Track 11 is also often mislabelled as "A Is To B As B Is To C".
A recording of Julie & Candy from the set, seemingly made direct from the soundboard, has also surfaced via YouTube. An attendee to ATP has said the video actually contains the same visuals projected/shown in the performance shown below [1]. The song was posted by user AtalantaFugiens. The source for the audio and video is unknown, but the video is on the favorites list of the official BoC YouTube account.
Recordings from this concert were never released. However, an audience bootleg from the show is widely available on mp3. Unfortunately, the quality is low, with heavy distortion in the lower frequencies.

On December 6, 2004, in the WATMM thread "Aphex Twin @ ATP", jbible mentioned that he was the one who had recorded BoC's performance. He provided some additional information about the recording:
On July 4, 2009, a new user named terekhova came forth on the Twoism forum with a partial recording he made at this show. While this recording consist of only two tracks, it has significantly better sound quality.
