When Henry Cow began recording "Unrest", they found they did not have enough composed material to fill the LP. Because of studio time constraints, they were forced to "improvise" and developed a "studio composition" process that involved improvising to tape, tape manipulation, loops, layering and overdubbing. The balance of the LP (tracks 2 to 5 on side 2) were "composed" in this manner. On parts of "Ruins" and "Linguaphonie", the bassoon, alto saxophone, drums and voice were recorded at half or double speed.
