U2's twelfth studio album, "No Line on the Horizon," will arrive March 3 from Interscope. A track list for the set, which was produced by Brian Eno, Daniel Lanois and Steve Lillywhite, has not been announced.

Following sessions in Fez, Dublin and New York, "No Line on the Horizon" was originally expected to be released before the end of 2008, but U2 was not fully satisfied with the material and continued working.

"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 told Billboard last month. "It's a great record, but it deserves the time. Labels need to work with artists to help them achieve their best work, not to jam records out that are half-baked or three-quarters baked."

"I'm always the one who underestimates how easy it is to simply 'put out the songs now.' If it was just up to me they'd be out already!," Bono told fans in September. "But early next year people will be able to start hearing what we've been doing. We want 2009 to be our year, so we're going to start making an impression very early on."

Among the songs expected to appear on the album are the title track, "Moment of Surrender" and "Unknown Caller." One source who has heard several of the songs in their early forms described them to Billboard as "amazing and a little out there. I hope they don't change anything."

"No Line on the Horizon" is the follow-up to 2004's "How To Dismantle an Atomic Bomb." U2 is expected to be back on the road in 2009, marking its first tour as part of a massive recent deal with Live Nation.
