U2 in Chile

"I've been with Edge where he can literally spend days working on the sound. He can just be experimenting with a sound for days, but when it actually comes to recording his part, he will record it in one go. It'a almost like you paint a wall, you spend all your time on the preparation and when you actually do the painting, it takes no time at all. That's what he was good at." - Steve Lillywhite on recording with Edge, 2021
