Raised in the vibrant London jazz scene, the students and friends Lynton Naiff (keyboards) and Grant Serpell (drums) tried to form a new band so they could be part of that exciting new hybrid music form, jazz-rock, which was emerging in the late 1960s. Together with bassist Mo Foster, guitarist Mike Jopp and fronted by Linda Hoyle, the new quintet performed for the first time in autumn 1968 under the name Affinity, named after an Oscar Peterson LP. The group caught the attention of Ronnie Scott. From then on, the band performed regularly at his legendary club as the support act for world-famous jazz greats.

In February 1970, they recorded their only, self-titled debut album at Trident Studios in London. It was produced by John Anthony with the assistance of sound engineer Robin Cable and was released later that same year on the cult label Vertigo. Their organ-driven progressive rock, characterised by psychedelic influences and with occasional ventures into the realm of jazz-rock through the use of a horn section, was well received by critics. Nevertheless, the album found hardly any buyers and the group disbanded in 1972. Their only LP, presented in an attractive gatefold cover designed by Keef, has become a classic over the years and is now regarded worldwide as a sought-after rarity.
