some leftover material from her score to Tron. Soon after, Carlos secured a deal with Audion Records, a smaller label, as she wished to "get away from that kind of big, monolithic government-like aspect that [she] had dealt with for so many years". In 1986, Audion released Beauty in the Beast, which saw Carlos experiment with just intonation, Balinese scales, and four new microtonal scales she devised for the album: Harmonic, Alpha, Beta, and Gamma. The album features the first instance of a 35-note octave. Carlos considers the album as the most important of her career. She followed the album with Secrets of Synthesis in 1987, her final album for CBS/Columbia, featuring several introductions and demonstrations of synthesized music from Carlos with audio examples from her previous albums. In 1988, CBS Records asked Carlos to collaborate with comical musician "Weird Al" Yankovic to release a parody of Peter and the Wolf by Sergei Prokofiev. Carlos agreed to the project, as she felt it presented a chance "to let your sense of humor out of the cage". Yankovic adapted and narrated its story, while Carlos rearranged the music with a "MIDI orchestra", her first venture using the digital interface. The album's second side also contains a humorous adaptation of The Carnival of the Animals by Camille Saint-Saëns titled "The Carnival of the Animals–Part II", with Yankovic providing funny poems for each of the featured animals in the style of poet Ogden Nash, who did similar for the original. Released in October 1988, Peter and the Wolf/Carnival of the Animals–Part II was nominated for a Grammy Award for Best Album for Children in 1989. 1990s–2000s To mark the 25th anniversary of Switched-On Bach, Carlos re-recorded the album with her set of digital instruments and recording techniques. Released in 1992 on Telarc Records, Switched-On Bach 2000 took roughly one and a half years to produce; Carlos estimated around 3,000 hours were invested in the project, which involved using several digital audio workstation software packages, including Pro Tools. A Moog synthesizer is only used once on the record; the rest is performed on 13 modern synthesizers. The album also marked her first venture into mixing in Dolby Surround sound. Carlos wrote the soundtrack to the British film Brand New World (1998), also known as Woundings, directed by Roberta Hanley and based on a play by Jeff Noon. Carlos explained the style of her music:
