And he reveals they haven't yet listened back to the work they've recorded so far. The band returned to the studio last year to start the follow-up to 2010's King Of Limbs. They've since taken a break and gather to continue the project next month.

Greenwood tells the Sunday Guardian: "We've certainly changed our method again. It's too involved to explain. We're kind of limiting ourselves - working in limits. It's like we're trying to use very old and very new technology together to see what happens."

He adds: "We've done a couple of months of recording and it's gone really well. We haven't listened to anything back yet, so at the moment we're all very happy. I guess we're going to go and listen to what we've done and see if we were right to be so happy.
