"I suppose I am the archaeologist, I will find the rough mix from four months ago that has the classic drum fill on it. Generally I can find it, these are the things you tick off in your subconscious - 'That's classic, whatever happens that is going to make the album' - and when you find that, you keep your hands on it. The subconscious is weird, if you really are consumed by something, it will keep working and sometimes it will get the answer. It tends to happen when you're really in it - and that's the way it's been for the last six months." - The Edge on working on All That You Can't Leave Behind, 2000
