|Birth name||Andrew Lee Isaac Vowles|
|Also known as||Mushroom|
|Born||10 November 1967|
Vowles grew up in Bath. The same time to Massive Attack, Vowles, along with Robert Del Naja, Grant Marshall, Nellee Hooper, and others were The Wild Bunch crew, named after a western by Sam Peckinpah. Several members of The Wild Bunch formed Massive Attack.
Vowles stayed 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 liking 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".
