One of my favorite concerts of all time from one of my favorite albums of all time. Various artist performed the songs along with Roger Waters each lending their own touch of understanding to his lyrics. The sound is incredible with the added choir and orchestra unfolding the rock written songs into the beautiful melodies me and my friends could hear when listening to it many years ago. As we listened to the album it was obviously conceptual and it was shown here in all its beauty but still having that edge. All with relevance. Classic piece of work. I feel sorry for the audience having to sit thru the building of a wall that prevented them from seeing the musicians.
