Next spring, U2 will show us all what they’ve been working on since dismantling a bomb.

Although the group had originally planned to complete its next project by the end of 2008, their 12th studio album is now scheduled for a March 3 release. (No Line on the Horizon will be available internationally on March 2.) The band’s desire to add more tracks is the reason for the delay.

“I met with the guys in U2, and they say to me, ‘You know what? This album needs two more songs, and it will be exactly what we have in mind.’ I go there and I listen, and I agreed with them,” Interscope-Geffen-A&M chairman Jimmy Iovine stated.

Horizon - which was produced by Brian Eno, Daniel Lanois and Steve Lillywhite - will most likely be accompanied by a 2009 concert tour.

The group’s last album, How to Dismantle an Atomic Bomb, was released back in 2004. It went on to sell an estimated 9 million copies and won the Grammy for Album of the Year in 2006.
