U2 is ready to release its first new album in more than four years on March 2. The new disc -- No Line on the Horizon -- follows 2004's How to Dismantle an Atomic Bomb.

No Line was recorded in Dublin, New York, London and Morocco, according to the band's label, Interscope Records. The album was originally to be released in November, but was delayed when frontman Bono wasn't happy with the final results, according to media reoprts.

The disc was produced with Brian Eno, Danny Lanois and Steve Lillywhite. Tracks recorded with producer Rick Rubin have been tossed out, Interscope says.

"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," Interscope chairman Jimmy Iovine told Billboard last month.

Billboard says one source who has heard some of the songs in their early form describes them as "amazing and a little out there."
