U2 have decided to scrap twelve months of songs and start their new album again from scratch.

The veteran rockers haven’t released an LP since 2004’s ‘How To Dismantle An Atomic Bomb’, but guitarist The Edge say the band are under no pressure to release any new material until they’re completely happy with it.

He tells CMUMusic.com, "We went into this project allowing ourselves the indulgence of making music without thinking about where it was going to end up."

However, he adds, "We're starting to get serious now.”
