"Had you given any thought to recording the new album in surround sound?
We did, actually. My initial intention was to release it in 5.1 at the same time as the CD, but we won't get around to finishing the mix until the tour and the summer holiday are over. We recorded all of the drums and orchestral stuff in surround. While I do like to keep the rhythm section more or less in stereo, I tend to bring some of the more fluid things — voices, keyboard textures — around from the front to the sides for a much wider effect. You have to get a feeling for the sounds that are possible and natural enough for your brain to deal with. I don't like to put too many instruments behind the listener."
