George Lewis is a groundbreaking trombonist and composer as well as the Edwin H. Case Professor of American Music at Columbia University. Lewis’ career as a musician has been closely tied to the Association for the Advancement of Creative Musicians, a group founded in Chicago in 1965 to nurture creative and experimental music. Since 1971, Lewis has performed and recorded with a number of the group’s members, including Muhal Richard Abrams, Anthony Braxton, and Roscoe Mitchell. Lewis is also well-known for his work with computers and electronic music, including his software Voyager, which listens to and improvises with human performers. Since the 1990’s, he has also achieved success as a scholar, notably with his 2008 book A Power Stronger than Itself: The AACM and American Experimental Music, which won the American Book Award in 2009.
