'Scratch My Back' is Peter Gabriel's first new studio album in nearly a decade. The album is the first part of a series of song exchanges in which Gabriel and other leading artists reinterpret each other's songs. Gabriel describes this as a very personal record with twelve songs performed only with orchestral instruments and voice. He made the choice not to include guitar or drums. The album's richly diverse sounds include the sparse romance of Lou Reed's "The Power of the Heart", the powerful musical journey of Elbow's "Mirrorball" an epic arrangement of Arcade Fire's "My Body Is A Cage" and further interpretations of Bon Iver, Paul Simon, Regina Spektor, The Talking Heads, David Bowie, Randy Newman, The Magnetic Fields, Neil Young and Radiohead.
