While 2001's Magnification received a full 5.1 mix by Tim Weidner, Yes' previous studio album—The Ladder—only had one song mixed in surround: the title track, "Homeworld (The Ladder)," mixed by Mike Plotnikoff. Featured as a bonus track on the House of Yes: Live From The House of Blues DVD in Dolby Digital, it was also included in lossless MLP on a promotional DVD-A featuring selections from both Magnification and House of Yes (pictured). The surround mix hews very closely to Plotnikoff's stereo mix from the original album (no surprise) in terms of tonality and relative levels, but makes fairly liberal use of the surrounds, with elements both discrete and shared with the front speakers placed there. I would liken the approach to Steven Wilson's, if not quite as refined and active. (Unfortunately, Plotnikoff's 5.1 mixes of the live House of Yes material pale in comparison, with mere ambience in the surrounds.)
So, purely from a mix perspective, how would you rate the surround mix?
I'd give it an 8. While not quite on the level of a Steven Wilson Yes mix, it's really very good and quite immersive.
(As an aside, this song was included in the soundtrack to 1999's Homeworld real-time strategy game.)
