I have to agree that this music was just made for surround. The mix is discrete as hell. And at the end of the album when they have the weird sound effects going around the room, while yes it's gimmicky, it's a great way to close out the album. All throughout the record there's stuff going on everywhere. This isn't background music. If you want to appreciate this disc, you need to sit in the sweet spot, close your eyes and concentrate on it. I like that they threw in "Lucky Man" as a bonus even though it was on a completely different album. They probably did this so that there was at least a "hit" (if you can call it that) that people might recognize which would help sell copies.
If you don't like pretentious super progessive keyboard-driven rock and roll, you might not like this disc. In the 70s, I'm told that the running joke about Emerson, Lake and Palmer was:
Q: How do you spell pretentious?
A: ELP
As a fan of Yes, Genesis, King Crimson, Jethro Tull and countless other progressive rock bands of that time, this album just works for me. I give it a 9.5, rounded up, a 10.
