“His music aimed always at the further extension of the horizons of jazz and sometimes ex­perimented with atonality and with a wide range of dissonant effects. Some elements offer a sharp and piquant con­trast, with clearly defined folk music roots and a savage, shouting, blues–derived intensity. Not for com­placent ears, Mingus’ music is the prototype of a new and vital generation of the 1960s just as Charlie Parker and Dizzy Gillespie were of the 1940s.” (Leonard Feather, The New Encyclopedia Of Jazz)
