A British jazz/fusion guitarist associated with the Canterbury Scene.

In 1975, a recommendation from fellow guitarist Allan Holdsworth led to him joining Soft Machine.

Between 1989 and 1993, he was a member of Danny Thompson's group Whatever, playing on the album Elemental (1990). Between 1988 and 1994, he also did a lot of touring in Germany with Dick Heckstall-Smith, recording two albums as the Dick Heckstall-Smith / John Etheridge Band.

In addition to countless one-off line-ups assembled for jazz gigs, he is involved in several long-term projects, including a guitar duo with John Williams, which released Live In Dublin - Places Between.
