The album is about voices. I want to get away from instruments and electronics, which was the world of my last album, ‘Vespertine.’ I want to see what can be done with the entire emotional range of the human voice - a single voice, a chorus, trained voices, pop voices, folk voices, strange voices. Not just melodies but everything else, every noise that a throat makes.
