 Is U2 a sound or is it a spirit? Especially Edge, it reinvented guitar essentially. I mean, I can say this, he's too modest too, but he's the most influential guitar player in 30 years. There's no one who will disagree with that. And the sound of the band had arrived and it had done very well over a couple of years. And I thought, well, I don't like the idea that it's a sound and it's like a formula or something.
