Isotope were one of the major (and earliest) British jazz-rock bands of the 1970s, coming along chronologically only just behind Soft Machine and Nucleus, the two UK pioneer bands in the genre. Isotope was formed by guitarist Gary Boyle in 1972. After about a year, the band signed with a major U.K. management company who got the band signed to a independent label which was owned by a film company and things really took off. By the time of their second and best-known album, Illusion, the band consisted of Gary, ex-Soft Machine bassist Hugh Hopper keyboardist Laurence Scott and drummer Nigel Morris. This version of the band lasted nearly 2 years and played hundreds of shows. Golden Section is over 65' of all unreleased material, taken from 3 different dates, all from the period when Hugh was a part of the band and lent his strongly distinctive style to the group; from the opening notes of the album, it's readily apparent that Hugh is in the house! More than half the CD is a program recorded by Radio Bremen in Germany for broadcast. During this time, the band included a fifth member, percussionist Aureo de Souza, who played with the group for several months during spring/summer 1975 and added a definite Weather Report-inspired flair, but whose tenure with the group has never before been documented on record or heard! In addition to the music, Golden Section includes a 12 page booklet with exclusive interviews with the musicians, conducted by Aymeric Leroy, that gives an overview of the entire history of the band and tells the full story of the period covered by these recordings. Also included are never-before seen photographs of the group.
