Murder Rock (Italian: Murderock - uccide a passo di danza; also known as Murder-Rock: Dancing Death, Slashdance and The Demon Is Loose!) is a 1984 Italian giallo film starring Olga Karlatos and Ray Lovelock, and written and directed by Lucio Fulci. Fulci recalled the producer forced him to turn the film into a musical with the music of Keith Emerson due to the success of "Flashdance".
Keith Emerson was hired for the job to create the melodious sounds for Lucio Fulci's Murder Rock after pressure was put on Fulci to transform the work into a musical.
