Lately the overarching narrative with respect to Peter Gabriel’s been his dialogue with other artists, be it musically or literally. This cover has nothing to do with Scratch My Back, the set of orchestral reinterpretations he released earlier this year. It’s for the Voice Project, a non-profit project that creates a “chain of songs,” each covered-artist then tagged to cover someone else in turn, and so on, in the same manner that Ugandan women have used songs to send messages to their abducted and relocated children, those kidnapped and forced into military efforts by Josephy Kony’s LRA. Here Peter discusses the project, the power of song, and the power of Tom Waits’s songs. And then he sings one.
