“One of the problems of concerts in the modern age is that people often have to come from the office … and they have all their quotidian concerns with them. They come, and they get a place — row number whatever, seat whatever — and they have to sit down. It’s a little like factory chickens. And we say, ‘Now it’s time for art, for the ultimate revelation.’ Length is also a problem, the idea that you have to have 90 minutes of music. It’s like going to the gym. It’s a stiff form — too stiff for me.”
