I sometimes feel a bit embarrassed to play guitar. There's something - I don't want to sound ungrateful - but there's something very old-fashioned and traditional about it. You meet kids today whose grandparents were in punk bands, really. It's very old and traditional, But then, you know, so is an orchestra and so is the string section.

I think It's a bit of a disappointment that a lot of people's Golden Age of music is still the '60s.

I think I'll always feel a little in awe whenever I see someone in their 20s or 30s carrying a cello or violin case - because I know, if they're doing it professionally, how many years of practice have gone into being able to make music with them. And the sounds they can make just hit me very hard, and feel full of limitless complexity.

I trust microphones, speakers and recordings less and less, and no longer buy into the idea that I can recreate at home, or in my earphones, the experience of hearing live acoustic instruments. The orchestra is already a set of speakers that react differently to each player, each room and each concert - it's that high level of uncertainly and unrepeatability that I like. The music is just soaked into the walls of a room straight from the instruments - and it's a one-off deal. The alternative - left speaker, right speaker - is kind of a compromise.

Every American college student goes to college with a hard drive. They take their laptop. There's not a CD player in sight.

Nothing's more exciting than a day in a studio with a string section - or more ruinously expensive. So it's good to feed that habit away from the band, especially if it means more experience for the next Radiohead string day.

I suppose subconsciously I was thinking in terms of having the scale of it matching the scale of the images. Hence the sort of string quartet, jazz band and electronic stuff.
