Bono and The Edge

"Sometimes we write in soundchecks, sometimes we work together in a room, oftentimes I might come in with a piece of music. Generally, though, it always finishes in the same way, with all of us in the same room, bashing it out, which I think is what creates the unique qualities of the band—the fact that there’s four people pulling and pushing at this piece to put it into some sort of shape." - The Edge on how U2 works, 1986
