From Massive Wiki
Andrew Lee Issac Vowles (born 10 November 1967, Bristol, also known as Mushroom, is a founding member of Massive Attack]].
Prior to Massive Attack, Vowles, along with Robert Del Naja (3D), Grant Marshall (Daddy G), Nellee Hooper, and others were the The Wild Bunch crew, named after a western by Sam Peckinpah. The Wild Bunch would eventually become Massive Attack.
Vowles remained a member of Massive Attack until shortly after the release of their third full-length album, Mezzanine, in 1998. Interviews with band members have pointed to differences of opinion in the direction the band should go; Vowles preferring a hip-hop direction while Robert Del Naja and Daddy G leaned more towards darker electronica themes. He also had expressed a dislike for touring, an activity which he characterised as "pimping".
Vowles' nickname "Mushroom" comes from the arcade game, 'Centipede'. The game was installed at Special K's Cafe, a popular hang-out spot in the mid 1980s for Vowles and his Wild Bunch peers.
Apart from his contributions to Massive Attack, Vowles also appears as a DJ and co-producer on 'Raw Like Sushi' Neneh Cherry's 1989 debut album.
