Elton Dean (28 October 1945 – 8 February 2006) was an English jazz musician who performed on alto saxophone, saxello (a variant of the soprano saxophone) and occasionally keyboard.
Dean was born Nottingham, England, moving to Tooting, London, soon after his birth. From 1966–67, Dean was a member of the band Bluesology, led by Long John Baldry. The band's pianist, Reginald Dwight, afterward combined Dean's and Baldry's first names for his own stage name, Elton John.
Dean established his reputation as a member of the Keith Tippett Sextet from 1968 to 1970, and in the band Soft Machine from 1969 to 1972. Shortly before leaving Soft Machine he started his own group, Just Us. From 1975 to 1978 he led a nine-piece band called Ninesense, performing at the Bracknell Jazz Festival and similar events. His own groups since then, usually quartets or quintets, have most often worked in the free jazz mode, with little or no pre-composed material. At the same time, he continued to work with other groups that are very composition-based, such as guitarist Phil Miller's In Cahoots, drummer Pip Pyle's Equipe Out, and various projects with former Soft Machine bassist Hugh Hopper.
