I interviewed composer and multi-instrumentalist Henry Threadgill on Oct. 28, 2013, the morning after his triumphant Zooid concert at the Library of Congress. We discussed his musical upbringing in Chicago, the Association for the Advancement of Creative Musicians (AACM), the story of his life-changing experience in Vietnam, his groups Air and Zooid, and his approach to composition and improvisation.
