Miles Davis & Gil Evans: The Complete Columbia Studio Recordings is a box set of music by jazz musicians Miles Davis and Gil Evans originally released on CD in 1996 and remastered and re-released in 2004. It collects work from 1957 through 1968 at Columbia Records recording studios. Miles Davis and Gil Evans had worked together on Davis's landmark album Birth of the Cool, recorded in 1949–1950. Evans was a distinguished soloist, but it was his role as arranger that is well-illustrated here with alternate and working takes.
