U2 - U2 Want To Be Better

U2 think their best work is yet to come.

The rockers - who released their twelfth studio album 'No Line on the Horizon' earlier this year - are always striving to do better and don't understand why other bands are not as ambitious.

Guitarist The Edge said: "It matters to us that we still make music that connects, and we are still capable of potentially doing our best-ever album.

"It's not a foregone conclusion that our best work is behind us. That still makes it really exciting.

"We get that. Sometimes I think, 'Why has it been so difficult for people in the past to maintain that?' We're still learning. We're still ambitious creatively, in terms of where we can take the band. There's an awful lot there for us."

The 'One' hitmakers insist their view isn't "arrogant" but because they don't feel any limitations or restrictions on their creativity.

The Edge added to Rolling Stone magazine: "We all genuinely believe it. It's not arrogance. It's because we are still hungry. There's no reason why we can't do this. You think about other art forms and artists — filmmakers, painters, sculptors. It doesn't follow that your best work is done in your late twenties, early thirties, and then it's downhill. Unfortunately, that's the way rock 'n' roll has panned out.

"Our only limitation is our ability to apply ourselves, to be hard-minded on our work. We push and push until we get to those special pieces of music, those lyrics. And it doesn't arrive on call. You can't turn it on."
