It marks a slight departure from the formula of the previous Pierre Moerlen's Gong's albums, Gazeuse! and Expresso II, towards more conventional pop/rock. "Aeroplane" and "What You Know" are short-form pop songs featuring lead vocals by Moerlen, the first time vocals appeared on a Pierre Moerlen's Gong album. Keyboards, some of which are provided by Steve Winwood, augment or even replace mallet percussion on a few tracks. Mike Oldfield contributes guitar on the title track.
