U2 enlists Dangermouse, will.i.am for new projects.

U2 confirmed that Danger Mouse is producing new album ‘Songs of Ascent’ and that he’s worked on at least 12 tracks, but he’s not the only one collaborating.
Bono says a club album is in the works, with Will.i.am, David Guetta and producer RedOne contributing. That album will “recall U2 remixes in the 1990s.” U2 aim to have a new album out by May of 2011.
