Eno - The Studio As Compositional Tool

"Which puts me in mind of the first piece on Music For Airports (Editions EG). I had four musicians in the studio, and we were doing some improvising exercises that I'd suggested. I couldn't hear the musicians very well at the time, and I'm sure they couldn't hear each other, but listening back, later, I found this very short section of tape where two pianos, unbeknownst to each other, played melodic lines that interlocked in an interesting way. To make a piece of music out of it, I cut that part out, made a stereo loop on the 24-track, then I discovered I liked it best at half speed, so the instruments sounded very soft, and the whole movement was very slow. I didn't want the bass and guitar - they weren't necessary for the piece - but there was a bit of Fred Frith's guitar breaking through the acoustic piano mic, a kind of scrape I couldn't get rid of. Usually I like Fred's scrapes a lot, but this wasn't in keeping, so I had to find a way of dealing with that scrape, and I had the idea of putting in variable orchestration each time the loop repeated. You only hear Fred's scrape the first time the loop goes around." from Downbeat, 1979
