Irish rockers U2 have delayed the release of their next album after studio sessions failed to go to plan.
The band has been working on its 13th studio album, the follow-up to 2009's No Line on the Horizon, with Gnarls Barkley star Danger Mouse and super-producer RedOne.
They had hoped to get the new material finished and ready for release within the next few months, but bassist Adam Clayton has revealed the recording sessions with RedOne just weren't working and their busy schedule now means they will have to delay further studio work.
The delay means fans are unlikely to hear the new album before late 2012.
Clayton tells Rolling Stone, "We had to have a meeting and look at the schedule to see if we could pick up any extra time to work on it. We just realized that we couldn't. To be honest, everyone was a bit gutted. But it was the only sensible decision (to postpone it)."
"We have to focus on what we do best, and the work we did with Danger Mouse came closest to that. We want to be in the clubs and make pop music as well as the thing U2 does, but in the end, the thing we did with RedOne doesn't feel like the right fit."
