Pierre Moerlen (23 October 1952, Colmar, Haut-Rhin – 3 May 2005, Sainte-Marie-aux-Mines, near Strasbourg) was a French drummer and percussionist, best known for his work with Gong and Mike Oldfield and as Pierre Moerlen's Gong.
Pierre Moerlen was born in Colmar (Haut-Rhin) on 23 October 1952, third of five children. His father Maurice Moerlen was a famous organist (one of his teachers was Maurice Duruflé) and his mother was a music teacher. All five Moerlen children learned music with their parents and all became musicians. Pierre's younger brother, Benoît Moerlen, is also a percussionist (he also worked with Gong and Mike Oldfield).
Pierre left Colmar for Strasbourg to learn percussion with Jean Batigne, founder of Les Percussions de Strasbourg. He was also a member of two rock and rock-jazz bands, including Hasm Congélateur (with included future Magma guitarist Gabriel Federow), whose most notable performance was the opening slot at the Seloncourt Festival in September 1972, headlined by Ange, Genesis and Robert Wyatt's Matching Mole.
In January 1973, Moerlen joined Daevid Allen's Gong, debuting on the Angel's Egg (1973) album. In June 1973 he was asked by Virgin Records's boss Richard Branson to play percussion with Mike Oldfield for the premiere of Tubular Bells (1973), to replace the incapacitated Robert Wyatt. Steve Hillage, guitar player of Gong, also took part. Between 1975 and 1987, beginning with Ommadawn (1975), Moerlen would be Oldfield's percussionist of choice for his albums and his tours.
