“I have a trick that I used in my studio, because I have these twenty-eight-hundred-odd pieces of unreleased music, and I have them all stored in iTunes,” Eno said during his talk at Red Bull. “When I’m cleaning up the studio, which I do quite often—and it’s quite a big studio—I just have it playing on random shuffle. And so, suddenly, I hear something and often I can’t even remember doing it. Or I have a very vague memory of it, because a lot of these pieces, they’re just something I started at half past eight one evening and then finished at quarter past ten, gave some kind of funny name to that doesn’t describe anything, and then completely forgot about, and then, years later, on the random shuffle, this thing comes up, and I think, Wow, I didn’t hear it when I was doing it. And I think that often happens—we don’t actually hear what we’re doing. . . . I often find pieces and I think, This is genius. Which me did that? Who was the me that did that?”

Eno’s strategies don’t always appeal to the musicians he works with. In Geeta Dayal’s book about the album, also titled “Another Green World,” the bassist Percy Jones recalls, “There was this one time when he gave everybody a piece of paper, and he said write down 1 to 100 or something like that, and then he gave us notes to play against specific numbers.” Phil Collins, who played drums on the album, reacted to these instructions by throwing beer cans across the room. “I think we got up to about 24 and then we gave up and did something else,” Jones said.
