Pierre Moerlen's Gong was an instrumental jazz fusion band led by French drummer Pierre Moerlen which developed as an offshoot of the psychedelic progressive rock band Gong founded and led by Daevid Allen. It was notable for the prominent use of mallet percussion, particularly vibraphone, in a jazz-rock context.
