Marty Ehrlich (born May 31, 1955) is a multi-instrumentalist (saxophones, clarinets, flutes) and is considered one of the leading figures in experimental or avant-garde jazz. Though born in St. Paul Minnesota, the portion of Marty's youth spent in St. Louis, Missouri, was particularly important. As a high school student at University City High School in St. Louis, the teenager came into contact with the influential Black Artists' Group (BAG, 1968-72) which was modelled after the AACM in Chicago.
