Jonny Greenwood

If I'm on a train, with headphones, MP3s are great. At home, I prefer CD or vinyl, partly because they sound a little better in a quiet room and partly because they're finite in length and separate things, unlike the endless days and days of music stored on my laptop.

When I have a creative insight, there is a high. I think back in the day, I made music as much as I did because it made me feel so good. I think you could argue that there is a creative addiction - but, you know, the healthy kind.

I would get records by Earl Scruggs... I would tune my banjo down and I'd pick out the songs note by note. Learned how to play that way. I persevered. There was a book written by Pete Seeger, who showed you some basic strumming and some basic picking... And I kind of worked out my own style of playing.
