I saw Dark Side of the Moon and Animals, in Montreal, outdoors. The sound system was insane. Could not tell the back of the venue from the front, so much sound piled in the back! And of course, massive stacks of speakers right and left, too. Quad. Real quad. Props were nuts too. Plane flies into the stage, explosion, movies, flying pig. Great show.
Saw the same show in Long Island.....at least I think i did.
Oh, how I remember those speakers! Yes! The train sounded as if it came from one side and ran over you to the other.
