Just pulled this one out. Hadn't listened to it (either in surround or stereo) in years. I had forgotten how amazing this one is. A fantastic discrete mix. Bringing the music from stereo to 5.1 actually does expose a little bit more of the musical imperfections that Mike has said always bothered him, but to me it's all part of this album's charm. Insane to think that he was only 19 years old when he recorded this.
If every 5.1 release was mixed this well, I'd be a very happy man. Lots of great discrete stuff happening in the rears, but never overbearing. I can't think of a single complaint on this one. The album is a defining moment in prog and the mix is exceptional. A perfect 10 from me. I'm baffled how anyone could have given it a 1 rating.
