This album became Songs of Innocence
Songs of Ascent Lyrics by U2
While not yet officially announced, Bono suggested that U2 were working on an album called Songs of Ascent.
U2 has played a couple of unreleased songs on the 360 Tour and it's assumed these songs are from sessions that were intended for the new album (or were possibly left overs from No Line on the Horizon).
