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".
