KATE BUSH: Well, I really didn’t see it as a substitute for a greatest hits package, but it was something I’d wanted to do for a few years. I guess I just kind of felt like there were songs on those two albums [The Sensual World and The Red Shoes (1993)] that were quite interesting but that they could really benefit from having new life breathed into them. I don’t really listen to my old stuff, but on occasion, I would either hear a track on the radio or a friend might play me one, and there was generally a bit of an edgy sound to it, which was mainly due to the digital equipment that we were using, which was state of the art at the time—and I think everyone felt pressured to be working that way. But I still remain a huge fan of analog. So there were elements of the production that I felt were either a little bit dated or a bit cluttered. So what I wanted to do was empty them out and let the songs breathe more. [Source]
