Neil, I think you're one of the few that really rave over Nocturama! I used to post a lot over the forum on Nick's site and this album got a rather ho-hum welcome upon release. While I don't count it as one of my top 3 NC albums I do think it's got a lot going for it and the reviews it got were a little harsh and undeserved. It's much like a good companion to "And No More Shall We Part" but with a few more leanings back towards his edgier side (Dead Man In My Bed and Babe I'm on Fire especially).
I'm just giving the 5.1 it's first spin. The mix is just fine thanks, I find it a nice improvement over the old 2 channel mix, a little more breathing room especially in the louder spots. The instrument spread on Bring It On works well with Warren's violin mostly in the rears. Okay, Rock of Gibraltar is still a bit of a throwaway, and I prefer the edit of Babe I'm On Fire (most days 15 minutes of it is just a little too much for me, and I've been listening to Nick since the Birthday Party days).
Good solid release, glad I bought it for sure. First listen score would be an 8 or 9 but I'll play it again before voting.
