Born in 1946, Gilbert was already 30 when Wire formed, a former art school student with a background in the British avant-garde music underground of the late '60s. This atypical interest is an enormous part of what made Wire so unlike the other bands of the first wave of U.K. punk, as the esoteric leanings of guitarist Gilbert and bassist Graham Lewis meshed with the somewhat more straightforward style of singer Colin Newman and drummer Robert Gotobed.
He resigned from Wire in 2004.
