WALL•E is the soundtrack to the 2008 Disney- Pixar film of the same name. Released by Walt Disney Records on June 24, 2008, it was mainly composed by Thomas Newman and orchestration is credited to Carl Johnson, JAC Redford, Thomas Pasatieri, and Gary K. Thomas. Newman previously scored Finding Nemo (2003) and all other Pixar films have been scored by either Newman's cousin Randy or Michael Giacchino or Patrick Doyle.
The soundtrack features excerpts from "Put on Your Sunday Clothes" and "It Only Takes a Moment" (both sung by Michael Crawford) from the soundtrack to the film Hello, Dolly! as well as an original song, " Down to Earth" by Peter Gabriel. Also featured in the film but not in the soundtrack are the classical pieces " Also Sprach Zarathustra" and " The Blue Danube", both of which are famous for their appearances in 2001: A Space Odyssey (which was one of the big influences of the movie). Neither Etta James's cover of the song " At Last" nor " Aquarela do Brasil", both of which were used in the theatrical trailers, appeared on the final cut of the film or on the soundtrack.
