暗黒の世界
This album contains an important performance in King Crimson's career, being the source of the improvisations "Trio" and "Starless and Bible Black", the Fripp instrumental "Fracture" and the intro to the song "The Night Watch", all of which were included, with some editing, in the 1974 album "Starless and Bible Black". Prerecorded excerpts of "(No Pussyfooting)" appear at the end of "21st Century Schizoid Man" similarly to what was included at the beginning of "USA".
