KaHil (El'Zabar) and the Ethnic Heritage Ensemble poster (1975)

Poster for a KaHil and the Ethnic Heritage Ensemble concert at Transition East in Chicago, IL on August 2, 1975 to celebrate the Association for the Advancement of Creative Musicians' (AACM) 10th anniversary. 

The Association for the Advancement of Creative Musicians (AACM), a non-profit tax-exempt arts organization co-founded in 1965 by Dr. Muhal Richard Abrams, Jodie Christian, Kelan Phil Cohran, and Steve McCall, is one of the oldest musicians associations in the United States. Since its founding in Chicago, Illinois in 1965, the organization's members have developed a body of work that encompasses the spectrum of traditional and contemporary music. Often strongly associated with free jazz, musicians frequently identified with the AACM include the Art Ensemble of Chicago, Anthony Braxton, Amina Claudine Myers, and Henry Threadgill, amongst many more. 

KaHil is now known as Kahil El'Zabar.
