John William Coltrane was an American jazz saxophonist and composer.
Though he was active before 1955, his prime years were between 1955 and 1967, during which time he reshaped modern jazz and influenced successive generations of other musicians. Coltrane's recording rate was astonishingly prolific, such that many albums did not appear until years after they were recorded.
He is regarded as one of the most important and influential jazz musicians, and one of the greatest musicians of the twentieth century. Along with tenor saxophonists Coleman Hawkins, Lester Young, and Sonny Rollins, Coltrane fundamentally altered expectations for the instrument.
