Boyle recorded two solo albums for Gull Records, “The Dancer” and “Electric Glide”. The band split as a result of management problems and the demise of British Lion Music, an offshoot of British Lion Films. There was one last line-up change in 1977, with only Boyle surviving from previous personifications, alongside Geoff Downes on keyboards (later in YES and ASIA), Steve Shone on bass and Colin Wilkinson on drums, but this new ISOTOPE never went beyond the rehearsal stage, only recording a couple of radio sessions. Brown and second keyboardist Zoe Kronberger were added at that point, but gigs became sparser. In March 1976, a third album, “Deep End”, was recorded (production duties were handled by BRAND X’s Robin Lumley), with Hopper playing on only his own composition “Fonebone”.

At that point, management problems resulted in a very difficult financial situation and Hugh Hopper decided to leave. In December 1975, Scott left and was replaced by Frank Roberts. Percussionist Aureo DeSouza was then added to the line-up for a European tour, and drummer Jeff Seopardie also reinforced the band for British dates later that year. Intensive touring in Britain followed, and a US tour was undertaken in March and April 1975. The writing was now shared equally between Boyle, Scott and Hopper. They then entered the studio, with Poli Palmer (ex-ECLECTION and FAMILY) producing, to record “Illusion”. The new line-up embarked on a UK tour in June and July, followed by dates in Germany and the Netherlands in August. They were replaced by Laurence Scott, a semi-pro keyboard player, and Hugh Hopper (formerly of SOFT MACHINE), whom Boyle had met while working with STOMU YAMASH'TA (Japanesse fusion band). Due to their success, it seemed that Brian Miller & Jeff Clyne were unable to handle the success, so they left in March of 1974.

In the same poll ISOTOPE picked up fourth place in both LP of the year. Even guitarist Gary Boyle was voted top 3 guitarist in Britain during the time due to a poll in Melody Maker magazine. In 1974, they release their debut album, which is self-titled in 1974 & become quite critically acclaimed & fortunately, the band gained equal acclaim for their live performances. The band soon signed with Gull Records in England and Motown in the USA, and started touring colleges and clubs around Britain, as well as touring on the continent such as: France, Germany and Scandinavia. ISOTOPE are Jazz-Rock British based quartet formed in 1973 by guitarist, Gary Boyle with Nigel Morris (drummer), bass player Jeff Clyne (bass) (Jeff previously was a member of Ian Carr’s Jazz-Rock group: NUCLEUS) and Brian Miller (keyboards).
