The score for RoboCop was composed by Basil Poledouris, who used both synthesized and orchestral music as a mirror to the man-versus-machine theme of the movie. The score alternates brass heavy material, including the memorable RoboCop theme and ED-209's theme, with more introverted pieces for strings, such as during RoboCop's home-coming scene. The music was performed by the Sinfonia of London conducted by Howard Blake and Tony Britton. The theme song also made its way into the arcade and NES RoboCop video games.
