He joined NYJO, with whom he subsequently toured nationally and also visited France and Bulgaria.

He left NYJO in 1970 and joined Graham Collier’s Septet, which starred at the 1971 Montreux Jazz Festival, winning two prizes.

Over the years Geoff has embraced both acoustic and electric jazz – in 1974 he joined Ian Carr’s Nucleus playing electric piano and Moog synthesiser. He played with this band for eight years, appeared on six albums and undertook many European tours. His composer credits for Nucleus included Rachel’s Tune from Snakehips Etcetera, Mysteries from In Flagrante Delicto and Solar Wind from Out of the Long Dark.

During the 1980s he recorded more of his original compositions with Strange Fruit and the Latin Fusion group Paz. In 1981 Geoff was commissioned to compose a suite for Camden Jazz Week, which was featured on both BBC radio and Channel 4 TV. In 1983 he visited New Zealand, where he worked with tenor saxophonist Brian Smith and recorded Southern Excursion, which was voted NZ Jazz Album of the Year. He was the musical director for a NZ film, Should I Be Good?, and played on several other soundtracks.

On returning to England he composed the incidental music for BBC TV’s eight part Nippon series and played on soundtracks on films, including The Man Who Fell to Earth, The Return of the Jedi and Space 1999, and in 1995 Geoff was arranger and musical director for the South African percussionist Julian Bahula’s album Wind of Change.

Around this time Geoff decided to invest in a home digital recording studio and in 1995 he launched his own CD label, Turret Records, with an album featuring his 10-piece Expanded band. A live album by Paz, Dancing in the Park, was the follow-up release. The band’s next album, Samba Samba, featured veteran vocalist and percussionist Frank Holder in a mix of songs and instrumentals written by Geoff and Dick Crouch.

Geoff has played regularly at Ronnie Scott’s with the Stan Robinson Quartet and has also accompanied many visiting jazz artists from the US, including George Coleman, Jimmy Giuffre, James Moody and Art Farmer.

Geoff’s Trio appeared at the Edinburgh Festival in 2006, receiving good reviews – more recently Geoff has been performing with folk fusion band Carmina.
