The PQ is outstanding and the concert shows the group having a good time. My only reservation is that Billy's vocals are somewhat lost in the mix and don't stand out the way they should. Musically the concert is great especially the guitar work. One other thing, be aware that the concert is choppy and skips from song to song / change in wardrobe to change with little editting. Most of the interplay between Billy and the audience is missing as a result of the "heat exhaustion"??? that was mentioned on the cover. I don't know for sure but after watching you don't feel you were at the concert (as a good concert blu-ray should make you feel) and that a lot was not included.
