Malcolm Cecil (9 January 1937 – 28 March 2021) was a British jazz bassist, record producer, engineer and electronic musician. He was a founding member of a leading UK jazz quintet of the late 1950s, the Jazz Couriers, before going on to join a number of British jazz combos led by Dick Morrissey, Tony Crombie and Ronnie Scott in the late 1950s and early 1960s. He later joined Cyril Davies and Alexis Korner to form the original line-up of Blues Incorporated. Cecil subsequently collaborated with Robert Margouleff to form the duo TONTO's Expanding Head Band, a project based on a unique combination of synthesizers which led to them collaborating on and co-producing several of Stevie Wonder's Grammy-winning albums of the early 1970s. The TONTO synthesizer was described by Rolling Stone as "revolutionary".
