There's a great interview with Brian Eno this week by Paul Morley for The Observer. Here is one of my favorite excerpts concerning his work with U2 and Coldplay. Follow the link to read the whole interview.
On working with U2 and Coldplay at the same time:
"It was fine. A few jokes. I felt like a philanderer who was with another woman and might make a slip and call her by the wrong name in bed. I had one computer that had all of the Coldplay stuff and all the U2 stuff. I had to very carefully label each folder because I was paranoid that I might end up with the same basic track for each group and I wouldn't notice until it was too late. There was a chance the same track might have appeared on both albums."
