Born in
Bristol to
Barbadian parents, Marshall joined the Bristol music scene as a member of the
sound system the Wild Bunch in the 1980s. The sound system included the other three founding members of Massive Attack,
Robert del Naja,
Tricky and
Andrew Vowles. At the time, he was one of the youngest DJs in the city. In 1986, The Wild Bunch disbanded. Del Naja, Vowles, and Marshall then formed the
trip hop group
Massive Attack in 1988, which are considered to have pioneered the
Bristol Sound along with
Portishead and Tricky. Between 2001 and 2005, Marshall was mainly absent from Massive Attack, with
100th Window being the only album he did not have major input on. Reuniting (minus Vowles) for
Heligoland and more recent projects, the group divided the production work between Marshall and Del Naja, who each worked on separate songs in their own studios, choosing their own collaborators. ==Other work==
