The producer of U2's new album has waxed lyrical about his work on the project, and made some pretty extravagant predictions of greatness.

"The president of the company is singing better than ever and the tracks are wildly innovative," Daniel Lanois enthused to the Boston Herald. "I would never have thought things would have gone this way. I believe, well, rock 'n' roll has been reinvented one more time." Aha.

"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," continued the long-time U2 collaborator. "They're very smart people. And 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."

Asked whether he was worried that their creative partnership, which stretches back over two decades, could become stale, Lanois replied, "Nobody wants repetition within this group of folks. We want to grow as artists and innovators and people. Life is not dull to us. So I can’t imagine that we’d ever get stuck in our ways." He also found time for a spot of extra praise for the Glorious Leader, saying "I also think Bono's lyrics get better with every record."
