Elliot Scheiner is a genius. I LOVE how he uses the rear phantom center, right behind your head! Gives me goosebumps!
Sorry for responding to a 14-year-old post, but I just auditioned a new speaker set with this disc and had the exact same thought. Both this one and In Absentia have a lot of rear center-panned information that gives an amazing holographic effect if you're sitting in just the right spot. Check out the clapping effect that fades from "Trains" into "Lips Of Ashes", or the distorted guitar solo towards the end of "Mellotron Scratch" - it's like they're literally right behind your head.
