The group first came together under the leadership of Australian-born Daevid Allen, an early member of Soft Machine who, after being denied reentry into the UK due to visa problems in 1967, remained in France and formed Gong largely around a group of French musicians including saxophonist/flautist Didier Malherbe, the only original member left by the time Gazeuse! was released in 1976.
While not titled as such, Gazeuse! was really the first release by a Gong offspring, Pierre Moerlen's Gong, which largely abandoned the psychedelic space rock of such early Gong releases as the classic Radio Gnome Trilogy (also featuring guitarist Steve Hillage) for a more jazz-rock fusion sound. Its immediate predecessor, Shamal (Virgin)—released earlier the same year and the first to feature the trifecta of Moerlen, vibraphonist Benoit Moerlen and vibraphonist/percussionist Mireille Bauer—hinted at the future direction of this Gong offshoot (the departed Allen later reuniting his vision of Gong, one that was more in-line with its early, hippy-aesthetic days). Shamal, however, featured vocals and was more progressive-leaning, thanks to Malherbe and bassist Mike Howlett's writing, and Hillage's echo-drenched guitar (he would leave the band, along with life partner Miquette Giraudy, before the album's February 1976 release).
Gazeuse! also features Francis Moze. A tremendous fretless bassist with a positively massive tone compared to American fretless innovator Jaco Pastorius, Moze demonstrated a similarly lithe dexterity as his American cousin that allowed him to lay down an unshakable groove while, at the same time, engaging in a more interactive way with the rest of his band mates. The album also includes an early appearance by Mino Cinelu, who would go on to greater fame with American fusion super group Weather Report and, in the last decade of his life, Miles Davis.
