Electronic music pioneer Wendy Carlos is credited with the music for three feature films: A Clockwork Orange (1971), The Shining (1980), and Tron (1982). However, her musical score for A Clockwork Orange is mostly made up of her arrangements of Ludwig van Beethoven’s work. Also, almost all the music that she and Rachel Elkind composed for The Shining was unused by director Stanley Kubrick. It did not appear in the film. Of the three films, Tron is the one in which audiences can hear the most of Carlos’s original compositions.
