Jazz.com‘s Ted Panken recently posted an in-depth two–part interview with George E. Lewis, author of A Power Stronger Than Itself: The AACM and American Experimental Music. In the interview Panken and Lewis engage in a detailed dialogue on the history, theory, as well as practice of one of the most influential jazz collectives of the 20th century—The Association for the Advancement of Creative Musicians.
From Panken’s preface to the interview:

A Power Stronger Than Itself is a landmark work. The bedrock of the text is an exhaustively researched linear narrative history, constructed on over 90 interviews from which Lewis traces keen portraits of numerous members; AACM archival records; encyclopedic citations from contemporaneous literature, both from American and European sources; and vividly recounted personal experience.
Furthermore, Lewis contextualizes the musical production of AACM members—a short list of “first-wavers” includes such late 20th-century innovators as Muhal Richard Abrams, who stamped his character on the principles by which the AACM would operate; the founding members of the Art Ensemble of Chicago (Roscoe Mitchell, Joseph Jarman, Lester Bowie, Malachi Favors, and Don Moye); Anthony Braxton, Leo Smith, Leroy Jenkins, Henry Threadgil, Amina Claudine Myers, and John Stubblefield—within both the broader spectrum of experimental activity and the critical theory that surrounded it, expressing complex concepts with rigorous clarity and elegant prose.
