Gong is a progressive/psychedelic rock band formed by Australian musician Daevid Allen. Their music has also been described as space rock. Other notable band members include Allan Holdsworth, Tim Blake, Didier Malherbe, Pip Pyle, Gilli Smyth, Steve Hillage, Mike Howlett and Pierre Moerlen. Others who have, albeit briefly, played in Gong are Bill Bruford, Brian Davison and Chris Cutler. Gong formed in 1967, after Allen?then a member of Soft Machine?was denied entry to the United Kingdom due to a visa complication. Allen remained in France where he and a London-born Sorbonne professor, Gilli Smyth, established the first incarnation of the band. This line-up fragmented during the 1968 student revolution, with Allen and Smyth forced to flee France for Deià in Majorca.
