All tracks are performed by the lineup of guitarist/keyboardist Robert Fripp, bassist/vocalist John Wetton, violinist/keyboardist David Cross and drummer Bill Bruford.

The live performance of "21st Century Schizoid Man" on CD Two was issued in 1975 as part of the album USA, featuring overdubbed violin from Eddie Jobson.

One such piece is "The Law of Maximum Distress", which appears in two sections, as it was believed at the time that the tape had run out in the middle of the performance.

As Robert Fripp notes in the CD jacket, "Most live recording follows the policy of two machines in use simultaneously to meet an eventuality such as this.

However, it was later discovered while compiling the 2009 Live in Zurich Collectors' Club release that the middle portion of the track had actually been severed from the tapes and dubbed over for inclusion on Starless and Bible Black, as "The Mincer".
