DTS-HD master audio is spacious with tight, deep bass and plenty of air between the instruments. Gigantic sound stage, especially when string section joins in. Vocal recording is dry with incredible nuance. You could literally hear her whisper above the full band & orchestra. Demo disc quality. Video is a little soft compared to, say, a nature documentary, but is basically crystal clear. Performance features stunning vocals & a very talented band. You probably either hate or love KD Lang but even home theater enthusiasts who are not into her music should consider owning this disc. This is a new standard for blu-ray concerts.
