American jazz great John Coltrane emerged in the 1950s, playing tenor and soprano sax with Dizzy Gillespie
, Miles Davis
and Thelonious Monk
. He is considered one of the greatest American musicians of the 20th century. A leader of "hard bop", in the 1960s he led his own groups and changed the face of jazz with experimentation and improvisation, his later recordings reflecting his belief that music was a form of spiritual expression. Sometimes called simply 'Trane, his recordings include Giant Steps
(1959), My Favorite Things
(1961) and A Love Supreme
(1964). In his later recordings he collaborated on avante-garde music with his wife, Alice Coltrane (b. Alice McLeod, 1937-2007), who had a career in her own right.
