Of the bunch of WB DVD-As that came out in the early 2000's, this has to be one of my favourites - especially compared to the stereo album, which barely moved the needle on my interest-meter.
On the surface this seems kind of like the precursor to a lot of knuckle-dragger boring 4/4 80's rock, but I think this album has a a lot more going for it than that stuff. There are a ton of nuances in both production and arrangement that really elevate it, especially in surround. The backing vocals, especially, are a real tour de force, and there doesn't seem to be any fear of fully using the 5.1 soundfield - there are plenty of great discrete moments in the rear speakers and even some quad-style swirling pans.
The tonality is a lot like some of Paul Klingberg's other 5.1 mixes - maybe a bit bright, and a bit too much compression on the loudest parts, especially for people who are used to Steven Wilson's more historically reverent approach to 5.1. I like the variety of approaches to 5.1 though, and whatever the shortcomings of this disc may be, they aren't big enough to stop me from enjoying the mix at all - and I think of myself as someone who's relatively picky about sound quality. I think with 5.1 often the first couple of listens can be disappointing in a way, because you have an idea in your head about how you'd do the placement of the instruments in the 5.1 soundfield and when things don't match up there's a sense of letdown. I think once you get past your preconceptions and listen to it for what it is, it's a really enjoyable album. One thing I do do with this disc is boost the bass by +2dB relative to my normal settings it gives the bass drum especially some added oomph.
I also think the disc itself represented a good value when it was released, with 4 demo tracks (also mixed in 5.1) along with some music videos and commentary and stuff. I agree that it's a better mix than Foreigner 4 as well - I found the high end on that disc boosted to the point of being sizzling and it made it a difficult listen as a result.
For me this disc is an easy 8, and maybe even a 9 if I'm feeling good.
