Okay, so I popped this in last night. It is the band at their peak and this is the best it's ever looked or heard. 3 completely different HD audio mixes that all seem pretty good. The main 5.1 mix is mixed as if you were at the show. The secondary mix is more like the 5.1 mix sans environmental cues. Lastly, there's a PCM Stereo mix for the purists with beefy fronts.
Visually I think the stuff that benefits most are the contrast levels. You will notice dust and noise here and there, but otherwise the blacks are straight ink. Admittedly, I think the audio is more of an upgrade than the visuals, but it's still the same great staging, camera shots, and amazing performance from David Byrne.
Still THE best concert video I've ever seen.
