“In modern recording one of the biggest problems is that you’re in a world of endless possibilities. So I try to close down possibilities early on. I limit choices. I confine people to a small area of manoeuvre. There’s a reason that guitar players invariably produce more interesting music than synthesizer players: you can go through the options on a guitar in about a minute, after that you have to start making aesthetic and stylistic decisions. This computer can contain a thousand synths, each with a thousand sounds. I try to provide constraints for people.”
