Blow-Up is a soundtrack album by American jazz pianist Herbie Hancock, featuring music composed for Michelangelo Antonioni's 1966 film Blowup. MGM Records released the album in the United States on 20 February 1967, and in the United Kingdom on 10 May. The album features performances by Hancock, trumpeters Freddie Hubbard and Joe Newman, alto saxophonist Phil Woods, tenor saxophonist Joe Henderson, guitarist Jim Hall, bassist Ron Carter and drummer Jack DeJohnette. Although Jimmy Smith is credited with playing organ on the album, some sources claim it was actually Paul Griffin who was at the sessions. The liner notes to a 2000s CD release indicate that Hancock first recorded the score in London with British musicians, but rejected the results and re-recorded the music in New York. According to a Library of Congress listing, additional uncredited musicians at the New York sessions included Don Rendell on tenor sax and Gordon Beck on organ. London sessions are said to have involved Hancock, Rendell and Beck, along with Ian Carr on trumpet, Pete McGurk on acoustic bass, and Chris Karan on drums. Hancock is also listed as being the arranger and music director.
