  The M-Base movement started in the 1980s, when a loose collective of young African-American musicians in New York which included Steve Coleman, Greg Osby, and Gary Thomas developed a complex but grooving sound.
  
  In the 1990s, most M-Base participants turned to more conventional music, but Coleman, the most active participant, continued developing his music in accordance with the M-Base concept.
  
  Coleman's audience decreased, but his music and concepts influenced many musicians, according to pianist Vijay Iver and critic Ben Ratlifff of The New York Times.
  
  M-Base changed from a movement of a loose collective of young musicians to a kind of informal Coleman "school", with a much advanced but already originally implied concept. Steve Coleman's music and M-Base concept gained recognition as "next logical step" after Charlie Parker, John Coltrane, and Ornette Coleman.
