Much like Duke Ellington before him, Charles Mingus' output was prolific. Over his near four-decade career, Mingus was behind a number of jazz firsts: he composed and recorded arguably the first jazz ballet - labelling his iconic LP 'The Black Saint and the Sinner Lady' as "ethnic folk-dance music." He also brought together elements of swing, bebop and R&B in ways that had never been heard before. Unlike some of his contemporaries, Mingus never shied away from his roots in gospel music and the blues. Rather, these textures became an integral part of his sound - often juxtaposed against elements from the free jazz movement.
