Of the 25 songs we've recorded there were 24 that we wanted to have on an album. That wouldn't have worked. So when one of our wise managers suggested the idea of considering two different album, it cleared the way for us.

I'm thrilled we've got a new single out, as singles were the way I first got into music as a child.

Hacking involves a different way of looking at problems that no one's thought of.

The thing is, it really did take us too long to get these recordings done. We've had our rough times in the studio in the past, but after four weeks most of the material would have been recorded. This time it seemed like it just goes on and on.

But for the first time, we haven't made a huge leap forward in sound from our last album. Fans who own Kid A should be able to get their heads around it.

There was this discussion to know how long the human ear was really receptive to the music. A 74 minute CD is too long. We thought about making two CDs, 35 minutes each... But the songs need to breathe.
