Irish rockers U2 have announced that there will be no U2 album or tour until 2015.

Fans had expected the album to be released later this year. The band--composed of Bono, The Edge, Adam Clayton, and Larry Mullen, Jr.-- has recently been working hard in the studio with producer Danger Mouse (Brian Burton). 

In a March 11 article in the NY Daily News, the band said that the delay was not true. "U2's album is planned for this year (and) is still on track and touring plans having been confirmed yet," said the band's representative in a statement. 

"We want (the new album) to come out this summer, but you don't want to let anyone down," Bono told USA Today early 2014.

Recent reports, however, say that the album will not be released this year. According to Billboard, the album has been pushed back until 2015, and the band has scheduled sessions with producers Ryan Tedder and Paul Epworth. 

A source was quoted as saying: "It seems to be taking longer for them to finish an album as they get older, but 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 band has already given some teasers, however. In the past months, U2 has released two tracks: "Ordinary Love," an Oscar nominated song featured in the film "Mandela: Long Walk to Freedom"; and "Invisible," which was released during the Super Bowl and was performed at "The Tonight Show." 

In a January interview with USA Today, frontman Bono said that they have been working on the new album for a while now. "In this band, a song isn't finished until it's being sold online, or in the shops. And even then, Edge might try to remix it," he added.
