The long wait may finally be over as U2 drummer Larry Mullen Jr. says the band should finally be wrapping up production this summer on a follow-up to 'No Line On The Horizon', which came out in 2009.

A few years ago it was reported that U2 had three albums' worth of music in the can, including traditional rock tunes, dance tracks and the more "meditative" material.

Recording sessions with producers Danger Mouse and Rick Rubin also supposedly took place, although the fate of that material remains unknown.
