暗黒の世界
The only songs recorded entirely in the studio were the first two tracks, "The Great Deceiver" and "Lament". "We'll Let You Know" was an entirely improvised piece recorded in Glasgow. "The Mincer" was another improvised piece, originally recorded in concert at the Volkshaus in Zürich but overdubbed with Wetton's vocals in the studio; The track was the edited-out middle section of a longer improvisation, the other parts released on "The Great Deceiver" as "The Law of Maximum Distress". "Trio", "Starless and Bible Black" and "Fracture" (the last of which Robert Fripp has cited as one of the most difficult guitar pieces he has ever played) were recorded live at the Concertgebouw in Amsterdam. Also recorded at the Concertgebouw was the introduction to "The Night Watch" (the band's Mellotron broke down at the start of the next section, meaning that the remainder of the song needed to be recorded in the studio and dubbed in later). In all cases, live applause was removed from the recordings wherever possible (although the remains of it can be heard by an attentive listener). The complete Amsterdam Concertgebouw concert was eventually released by the band in 1997 as "The Night Watch".
