Carlos' first project with Franklin began around 1980, when The Walt Disney Company asked her to record the soundtrack to its science fiction feature "Tron" (1982). Carlos agreed, but was not interested in composing solely with electronic music, as she wished to incorporate an orchestra with her musical ideas. She recalled their demands were "tightly specified ... there wasn't a lot of elbow room, and that made it fun". The score incorporated Carlos' analog and digital synthesizers with the London Philharmonic Orchestra, the UCLA Chorus, and the Royal Albert Hall Organ. "Tron: Original Motion Picture Soundtrack" was released in 1982 and reached No. 135 on the "Billboard" 200. Carlos intended to release her scores on her own album, but Columbia/CBS showed a lack of interest in the prospect.
