By the late 1970s Percussionist Pierre Moerlen had taken over the leadership of GONG and had steered the band away from Psychedelic Space Rock and took the band into a Jazz Rock direction, one in which the band excelled. After recording several albums with Virgin, with the band now featured Hansford Rowe on bass, Ross Record on guitar, Benoit Moerlen on vibes and Francois Causse on percussion.
Moerlen signed with Arista Records in 1978 and recorded this excellent album partially in Mike Oldfield's studio. Oldfield guested on the superb lengthy title track with fellow guest Steve Winwood, whilst Mick Taylor appeared on the track 'What You Know'.
