For the 1959 studio album recording "Kind of Blue", Miles Davis who lived May 1926–September 1991, led a sextet featuring saxophonists John Coltrane and Julian "Cannonball" Adderley, pianist Bill Evans, bassist Paul Chambers, and drummer Jimmy Cobb, with new band pianist Wynton Kelly appearing on one track – "Freddie Freeloader" – in place of Evans.

Music critics and some Jazz aficionados have said, " "Kind of Blue" popularized a new approach to improvisation. Rather than basing its 5 tunes on a rigid framework of changing chords, as was conventional for post-bop music, Davis and Evans wrote their music with a more limited set of scales in different modes." The album "Kind of Blue" was recorded at Columbia's 30th Street Studio in New York City, New York and was released in August of 1959 by Columbia Records. In 2002, the album was one of 50 recordings chosen by the US Library of Congress to be added to the National Recording Registry.

William John Evans (Bill Evans), an American jazz pianist and composer, was born in August 1929 in Plainfield, New Jersey. He lived for 51 years and died in New York, New York from cirrhosis and hepatitis in September 1980 at The Mount Sinai Hospital. When he recorded music, he mostly worked as the leader of a trio. He is now remembered for his use of impressionist harmony, interpretation of traditional jazz repertoire, block chords, and trademark rhythmically independent, "singing" melodic lines which continue to influence jazz pianists.
