American jazz trumpeter and occasional film composer. Began professionally with the orchestras of Glenn Miller and Ray McKinley. After national service, he formed his own band which performed in New York's Greenwich Village. From the late 1950's, he played a more progressive style of jazz, working with smaller groups, including the George Russell Sextet. During the 1960's, he made a series of successful records for CBS, at which time he was called "the father of the time revolution" in jazz. He was also a huge hit at the 1966 Monterey Jazz Festival.
