The Edge told Rolling Stone that spending time with The White Stripes leader and Jimmy Page for recent documentary 'It Might Get Loud' influenced his style.

The guitarist explained: "I was just fascinated with seeing how Jimmy played those riffs so simply, and with Jack as well."

U2 singer Bono added that the songs have also been inspired by world events, with closing album track 'Cedars Of Lebanon' seeing the singer in the role of a war correspondent.

"On this album, you can feel what is going on in the world at the window, scratching at the windowpane," he said.

U2's twelfth studio album, their first since 2004's 'How To Dismantle An Atomic Bomb', is released on March 2.
