Bono 'finds comfort' in songwriting

Bono has revealed that writing U2's new album No Line On The Horizon helped him to find comfort in an "intimate place".

The singer admitted that his public profile in the world of politics and activism made him appreciate his time with the band more.

"I have learned to really value the interior life of being an artist and a writer and being in U2. It's become a very private and special place," he told The Observer.

"The songs have become more intimate. I wanted to get to an intimate and inner place. I wanted to get away from subject and subject matter into pure exchange."

Bono added that his experiences outside of music provided inspiration for the group's twelfth studio album.

"It's a very personal album. These are very personal stories even though they are written in character and, in a way, they couldn't be further from my own politics. But, in the sense of the peripheral vision, there's a world out there," he said.

U2 release No Line On The Horizon on March 2.
