Birth of the Cool is a compilation album by American jazz musician Miles Davis, released in 1957 on Capitol Records. It compiles eleven songs recorded by Davis's nonet for the label over the course of three sessions during 1949 and 1950. Featuring unusual instrumentation and several notable musicians, the music consisted of innovative arrangements strongly inspired by classical music, and marked a major development in post-bebop jazz. As the title implies, these recordings are considered seminal in the history of cool jazz. The majority of the recordings on the record are under three minutes.
