b. 28 August 1941, Isleworth, Middlesex, England. Marshall is one of the most impressive drummers Britain has produced, equally powerful, flexible and reliable in rock, jazz or fusion. He played at school, but became more heavily involved with music while reading psychology at university. He studied drums privately with Allan Ganley and Philly Joe Jones, and worked with Alexis Korner’s Blues Incorporated (1964), Graham Collier (1965-70), Nucleus (of which he was a founder member with Ian Carr in 1969, and to which he returned in 1982), Mike Gibbs, Jack Bruce (1971-72), and, in February 1972, he began his long-term membership of Soft Machine. On leaving the band he joined Eberhard Weber’s Colours (1977-81). He has been a regular associate of John Surman over many years, and has also worked with Michael Garrick, Keith Tippett, Chris McGregor, John McLaughlin, John Taylor, Graham Bond, Mike Westbrook, Tubby Hayes, Jaspar Van’t Hof, Kenny Wheeler, Gil Evans, Alan Skidmore, Ronnie Scott, Arild Andersen and many others, including those in the contemporary classical field and in session work.
