The Association for the Advancement of Creative Musicians (AACM) is an American nonprofit organization, founded in 1965 in Chicago by pianist Muhal Richard Abrams, pianist Jodie Christian, drummer Steve McCall, and composer Phil Cohran. The AACM is devoted "to nurturing, performing, and recording serious, original music," according to its charter. It supports and encourages jazz performers, composers and educators. Although founded in the jazz tradition, the group's outreach and influence has, according to Larry Blumenfeld, "touched nearly all corners of modern music." Per the AACM, it "pays homage to the diverse styles of expression within the body of Black Music in the USA, Africa and throughout the world."

Background

By the 1960s, jazz music was losing ground to rock music, and the founders of the AACM felt that a proactive group of musicians would add creativity and outlet for new music. The AACM was formed in May 1965 by a group of African-American musicians in Chicago centered on pianist Muhal Richard Abrams, who had organized the Experimental Band since 1961. The musicians were generally steadfast in their commitment to their music, despite a lack of performance venues and sometimes indifferent audiences. From 1969 the AACM organised a music education program for inner-city youths. In the 1960s and 1970s AACM members were among the most important and innovative in all of jazz, though the AACM's contemporary influence has waned some in recent years. Many AACM members have recorded widely: in the early days on the Delmark Records Avant Garde Jazz series and later on the Black Saint/Soul Note and India Navigation labels, and to a lesser extent on the Arista Records and ECM labels.

The musical endeavors of members of the AACM often include an adventurous mixing of avant-garde jazz, classical, and world music. The AACM also ran a school, The AACM School of Music, with classes in all areas taught by members of the AACM. The AACM also had a strong relationship with an influential sister organization, the Black Artists Group (BAG) of St. Louis, Missouri. The AACM has received aid from the MacArthur Foundation and has a strong relationship with Columbia College. A Power Stronger Than Itself: The AACM and American Experimental Music by AACM member George E. Lewis, which documents the AACM's history, has been published by the University of Chicago Press (May 2008).

In 2015, a 50-year retrospective exhibition of art, music and group-related artifacts, entitled, "Free at First", was held at the DuSable Museum of African American History. In the third decade of the 21st century, AACM members continue to produce vibrant avant-garde jazz and jazz-influenced music in Chicago and elsewhere.
