The
Great Black Music Ensemble, with almost 40 members, has long been an
avant-garde force in jazz. CDBaby.com asserted that the ensemble
brings "the excitement of new sounds and rhythms, while
incorporating the traditions of black music including funk, reggae,
bebop, swing, and more" to its music. The group is one of two bands
connected to the Association for the Advancement of Creative
Musicians (AACM), a group that has made "unparalleled contributions
to modern music," according to JazzPolice.com. Before 2005, the
ensemble was known as the AACM Big Band.
