U2 producer talks about their new album

U2's producer Daniel Lanois, has spoken on about his time with the band and their new album.

Speaking to the Boston Herald Lanois said Bono's voice is sounding great and the band have "reinvented" the genre of rock 'n' roll again with the upcoming record.

He said: "The president of the company is singing better than ever and the tracks are wildly innovative. I would never have thought things would have gone this way. I believe, well, rock 'n' roll has been reinvented one more time."

Lanois also revealed why the relationship between him and U2 has continued for so long - the producer has worked on six albums, including 'The Unforgettable Fire' and 'The Joshua Tree' in 1984 and 1987.

"I like those people for their appetite for innovation. They want things to be new and fresh, and they never get stuck on how the band should sound," explained Lanois. They're very smart people. And (Brian) Eno and I just have a lot of fun with them, especially for the first 20 or 30 per cent of the record. During those first sessions, it's no-holds-barred, we take on anything that comes our way."

He added: "I also think Bono's lyrics get better with every record."

The follow-up to 2004's 'How To Dismantle An Atomic Bomb', due early next year, is strongly rumoured to be called 'No Line On The Horizon'.
