Lush Life was composed by Billy Strayhorn, begun when he was just eighteen years old in 1933 and refined over the next several years before being completed around 1936. Originally titled Life is Lonely, the piece is a sophisticated jazz ballad written in D-flat major, featuring an extended introductory verse that functions almost as a separate composition, setting vivid images of loneliness and glamour before the main theme arrives. The harmony is richly chromatic with unexpected modulations, making the tune both emotionally resonant and technically demanding for performers. Strayhorn kept the piece as a private project for years, performing it at parties and during his 1938 audition for Duke Ellington, but not recording it until a Carnegie Hall performance in November 1948 with vocalist Kay Davis and the Ellington Orchestra. That recording was not released until 1991. Nat King Cole recorded the first commercial version in 1949, and Sarah Vaughan's celebrated 1956 rendition helped establish the tune in the wider repertoire. John Coltrane recorded a landmark instrumental version in 1958 featuring Donald Byrd on trumpet and Red Garland on piano, exploring the composition's harmonic depth at length. Clifford Jordan also took on the tune in 1960, with Cedar Walton on piano. Widely regarded as one of the most harmonically intricate and lyrically profound pieces in the jazz canon, Lush Life has been covered hundreds of times and remains an enduring standard.
