In addition to Ligeti, Kubrick also enjoyed a collaboration with composer Wendy Carlos, whose 1968 album "Switched-On Bach"—which re-interpreted baroque music through the use of a Moog synthesizer—caught his attention. In 1971, Carlos composed and recorded music for the soundtrack of "A Clockwork Orange". Additional music not used in the film was released in 1972 as "Wendy Carlos's Clockwork Orange". Kubrick later collaborated with Carlos on "The Shining" (1980). The opening of the film, in which the camera follows Jack Torrance's yellow VW beetle through the mountains to the Overlook Hotel, employs Carlos' eerie rendering of "Dies Irae" (Day of Wrath) from Hector Berlioz's "Symphonie Fantastique".
