Gary Winston Boyle (born 24 November 1941 in Bihar, India) is a British jazz fusion guitarist.
Boyle's family moved to England when he was eight years old. In his teens he started playing small clubs and then in 1962 relocated to Hamburg to play R'n'B in The Top Ten Club. Boyle returned to England in 1964 to play in Millie Small's backup band, opening for The Rolling Stones in sold-out tour. He then worked in Dusty Springfield's band The Echoes and became a member of Brian Auger and the Trinity. After attending the Leeds College of Music, in 1969 Boyle briefly joined Dorris Henderson's folk rock band Eclection, before returning to Brian Auger once more in June. For three years in the early 1970s he worked as a session musician with musicians Keith Tippett, Mike Gibbs, Mike Westbrook, Soft Machine,Stomu Yamashta's short-lived band "East Wind", Bert Jansch and Norma Winstone.
In 1973, Boyle founded the jazz fusion band Isotope with Jeff Clyne (bass), Brian Miller (keyboards) and Nigel Morris (drums). This line-up gigged around the United Kingdom extensively, and released their first, eponymous, album in 1974 on Gull Records. Examples of their live work can be heard on "Isotope and Gary Boyle: Live at the BBC" (Hux Records).
Following the departure of Jeff Clyne and Brian Miller in March 1974, Laurence Scott (keyboards) and Hugh Hopper (bass, formerly of Soft Machine) joined Boyle and Morris. This line-up toured Europe twice and the United States once, and recorded Isotope's second LP "Illusion". Live sessions from Germany can be heard on "Golden Section" (Cuneiform Records), with some tracks featuring Aureo de Souza on percussion.
Isotope's final album was "Deep End", released in 1976 (on Gull). The band's line-up had changed again, with Zoe Kronberger and Frank Roberts (keyboards) and Dan K. Brown (bass) replacing Scott and Hopper, although Hopper composed one tune for this album, "Fonebone", featuring himself on bass and Laurence Scott on keyboards.
Since Isotope disbanded Boyle has pursued a solo career, and has taught music in several English institutions.
