After ripping this disc years ago, I put it on a shelf in another room, and FORGOT about the disc AND the rip, lol... last night while browsing my hard drive I rediscovered it and gave it a first listen. The musical content is killer. The surround mix has plenty of discrete activity throughout (although some songs are more conservative than others), and the surround elements are not merely limited to horns/ keyboards... you also get some nice rhythm guitars and some cool panning effects from time to time (such as the vocals moving around the room on "Helpless Dancer"). I agree with others who have mentioned the levels from song to song can be uneven... for example "Quadrophenia" is quite a bit lower in level than most of the other songs (although that is easily remedied in Audacity if you rip your discs). The bass tends to be a little weak on many songs, but again, a boost here and there of the LFE channel in Audacity helps quite a bit (I think on "The Rock" the bass is isolated in the center channel, so I just boosted that channel and it sounds great). The only thing I'm a bit disappointed with is the closing track, "Love Reign O'er Me", which I was really looking forward to... it just sounds a little underwhelming to me, maybe a little muddy? The synthesizers on the track are a bit buried, as are the lead vocals. Luckily, there's a dry lead vocal in the center channel that can be boosted, so that helps. It's still a good sounding track... I guess I just had higher expectations after hearing how great some of the other tracks sound ("The Real Thing", "Quadrophenia", "I'm One", "5:15", among others). I'm glad I have this as part of my Who surround collection (along with the Tommy blu-ray and various DIY mixes from Rockband stems). I think I prefer the Tommy mix over this one, though (with the recommended channel swap putting the drums in the front left). I'll give Quadrophenia an 8.
