But there is another way of thinking about the Third Stream: not as a movement, but as an elastic sensibility or structure of feeling among musicians who work along the increasingly porous borders between contemporary classical music and avant-garde jazz. Threadgill – who won the Pulitzer Prize in composition this year – is one of many jazz artists whose work could be described as Third Stream. The trumpeter Wadada Leo Smith is another. Both Threadgill and Smith are founding members of the Association for the Advancement of Creative Musicians, a black musicians’ collective established in Chicago in 1965. They never called their work ‘Third Stream’, but many of the AACM’s composers were steeped in contemporary classical music, particularly the work of Cage, Boulez and Stockhausen.
