Jackie Mittoo （3 March 1948 – 16 December 1990） was a Jamaican- Canadian keyboardist, songwriter and musical director. He was a member of The Skatalites and musical director of the Studio One record label. 　　Keyboard virtuoso Jackie Mittoo was among the true legends of reggae — a founding member of the Skatalites and an extraordinarily prolific songwriter, he was perhaps most influential as a mentor to countless younger performers, primarily through his work as the musical director at the famed Studio One. Born Donat Roy Mittoo in Browns Town, Jamaica on March 3, 1948, he began playing keyboards at the age of four, and was rarely far from a piano through his teen years, performing professionally in groups including the Vagabonds and the Vikings. He frequently skipped school to play with the house band at nearby Federal Studios, and it was there that he met producer Coxsone Dodd, who recruited Mittoo for recording sessions when the scheduled pianist failed to appear on time. While attending Kingston College, he began jamming with fellow student Augustus Pablo, and they eventually formed a trio — the Jackie Mitree — which performed his original compositions.
