In 1979, Karl Jenkins, who had been a member of Soft Machine from May 1972 to the band's split in December 1978, was among a number of top session musicians put together for an ad hoc band called Rollercoaster, recording a Stevie Wonder tribute album called Wonderin' (1980). After that album was completed, a number of the Rollarcoaster musicians decided to record another album together, this time under the Soft Machine name.[2] Some of the musicians involved in the project would be part of Soft Machine's next live line-up, which played a six-night residency at Ronnie Scott's in 1984.
