Seven is the seventh studio album by Soft Machine, released in 1973. Roy Babbington, who had previously contributed to Fourth [MOVLP1601] and Fifth [MOVLP1599] on double bass as a session musician, replaced Hugh Hopper on bass guitar, who left to begin a solo career. Their unique take on jazz rock was groundbreaking. Seven is a highly diverse album combining minimal, spacey elements and some great instrumental jamming. It was also the last of their studio releases to carry a numbered title.
