In the series of programmes celebrating Ornette Coleman at 70, Alyn Shipton surveys the saxophonist's work in the sixties, when Coleman made a triumphant return to the concert stage at Croydon's Fairfield Halls after a three-year absence. At this point Coleman took up violin and trumpet, and his unorthodox ideas are assessed by George Russell and Wallace Roney. Coleman's son Denardo looks back on his first recordings with his father's band, which he made at the age of nine, and saxophonist Dewey Redman recalls the famous New York Is Now! sessions.
