Blow-Up is a soundtrack album by American jazz pianist Herbie Hancock, featuring music composed for Michelangelo Antonioni's 1966 film Blowup.

[4] 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.

[5] 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.

[6] 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.

[6] The album also includes "Stroll On" by the Yardbirds, a rewrite of their version of Tiny Bradshaw's "Train Kept A-Rollin'", featuring both Jeff Beck and Jimmy Page on lead guitar.
