Sound of Superman is a companion album to the soundtrack of the Warner Bros. film, Superman Returns. It features performances both original and cover by various up and coming artists, as well as established ones, including the final track on the album performed by Sara Routh, the sister of the actor portraying Superman in the film, Brandon Routh. All the songs on the album are based either on the character of Superman himself, or at the basic concept of what a hero really is. None of the songs actually appear in the film, although “The Rescue” was featured in a TV spot for Superman Returns.
