Bono says that U2 have revisited their punk roots on their upcoming new album, namechecking Talking Heads, The Ramones and electronica as influences.
Speaking to The Sunday Independent at the launch of his niece Leah Hewson's art exhibiton Cusp, the I Threw a Brick Through a Window singer said: "At the start of making this album we listened to the music that made us want to form a band in the first place.
"We visited everything from punk rock, The Ramones, Talking Heads, right through to electronic stuff, so it's all the stuff that made us want to be in a band."And the sound of the new album? Well we kind of put it in a blender. When we make an album, usually it still ends up sounding like us, which I guess is a good or a bad thing depending on where you stand."
"But with this one, this is not a version of us you have ever heard before, that's for sure."
The band have said the new album, which will be their 13th studio collection, is due for release early in 2014.
