Bono continues to ride two horses in all this. Yesterday he was holed up in a studio in the south of France with the rest of his band working on the next U2 album.
"We're just beginning the processes. We did some recording in Morocco last year. All the band went to an amazing religious music festival in Fez with some incredible sufi singers. It was a real humbling thing for a punk rock shouter, listening to these people who just close their eyes for 40 minutes and sing the most sophisticated melodies.
"We got this little riad, a small hotel with a courtyard in the middle and set up the band there, with a square of sky over our head. The two great catalysts of U2's recording life, Brian Eno and Daniel Lanois, joined us. We'd record during the day and then disappear into windy streets of the medina at night.It was an inspiring experience and a drummer's paradise."
Now, he says, they are trying to get their heads around what they recorded. "World music this is not," he says, though U2 fans will "feel the difference". Polyrhythmic is the word he chooses with a self-deprecating laugh. "U2 in dancefloor shock. Normally when you play a U2 tune, it clears the dancefloor. And that may not be true of this. There's some trance influences. But there's some very hardcore guitar coming out of The Edge. Real molten metal. It's not like anything we've ever done before, and we don't think it sounds like anything anyone else has done either."
I don't know about you, but I am very, very interested. Trance? Hardcore guitar? Molten metal? Sounds good to me =D
