" the Chicago Symphony was in a class by itself. Fritz Reiner, the famous Hungarian conductor, was fascinating to watch. He was somewhat stout, hunched over with round shoulders, and his arm and baton movements were tiny—you almost had to look at him with binoculars to see what he was doing. But those tiny movements forced the players to peer at him intently, and then he would suddenly raise his arms up over his head and the entire orchestra would go crazy. "
