Despite teasing their fans for several months, including a high-profile song that premiered during the Super Bowl, U2 will not release a new album or tour in 2014.

Billboard broke the news today (March 7), confirming with several sources that sessions with producer Danger Mouse, arguably the hottest producer in the indie world today, have hit a bit of a snag. They have brought in Ryan Tedder (OneRepublic) and Paul Epworth (Adele) to help out.

"It seems to be taking longer for them to finish an album as they get older," an unnamed source said, and quickly spun the negative into a positive by adding that "the great thing about U2 is that the whole of a record is always better than the sum of its parts. That magic that the band always seems to capture...they have yet to capture it."

The article also states that U2 were planning to announce a Fall 2014 tour later this month, but that has now been postponed until the following summer to correspond with the new record.

In February, U2 offered a new song, 'Invisible,' as a free download for a day as part of a fundraising effort for Bono's charity, (RED), which helps fight the global spread of AIDS. They chose 'Invisible' because it was "the first one we finished." A second from these sessions, 'Ordinary Love,' was featured in the film 'Mandela: Long Walk to Freedom' and nominated for an Academy Award.
