Ok I watched the two shows (or at least a good portion of both shows) last night. I agree that the Santana show is kick @$$. Great visual quality, sound quality, and performance. It rocked in a jazzy sort of way....day.....oh
I would use this disc to show of the sound and visual quality of my system. It is on par with the Cream, Eagles, and NIN discs.
The Deep Purple concert was a bit of a disappointment after seeing the Santana concert. The picture quality was great but the lighting design did not really make good use of HD. It was very dark. However when they went to close ups with enough light you could tell the HD quality was there. The sound mix was just ok. It just seemed that the vocals were buried (this may have been intentional). The performance was decent too but nothing over the top. Now don't get me wrong if you like Deep Purple get the disc for sure. If you are a fringe listener I would rent it first. So to sum up it is not a good HD Demo disc but it is a high quality disc that Deep Purple fans should enjoy.
I do not have the Yes concert yet but I will keep my eye out for the disc.
For both discs I thought the DTS-HD sounded the best.
