U2 have recruited Gnarls Barkley star Danger Mouse to produce their next album.
Frontman Bono tells fans the new release could be out early in 2011, because "it's just happening so easily".
The group is also working on new "club" album, which will feature collaborations with will.i.am and David Guetta, among others.
Bono tells The Age, "U2's remixes in the 1990s were a real treasure. So we wanted to make a club-sounding record. We have a pile of songs."
