Grantley Evan Marshall (born 18 December 1959), also known by the stage name Daddy G, is a British DJ and a founding member of the band Massive Attack.

The sound system included the other three founding members of Massive Attack, Robert del Naja, Tricky and Andrew Vowles.

[3] 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.

[4] 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.

[5] 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.
