Phillips' 1968 recording of solo bass improvisations, issued as Journal Violone in the USA, Unaccompanied Barre in England, and Basse Barre in France, is generally credited as the first solo bass record. A 1971 record with Dave Holland, Music from Two Basses, was probably the first record of bass duets. In the 1970s he was a member of the well-regarded and influential group The Trio with saxophonist John Surman and drummer Stu Martin. In the 1980s and 1990s he played regularly with the London Jazz Composers Orchestra led by fellow bassist Barry Guy.
