People forget the opposite end of the performance. "Electric recording" was not invented until 1926. I have a 1925 picture of Louis Armstrong's Hot Five playing into a huge horn terminating to a diaphragm holding a needle to a spinning lacquer. Louis had to stand behind the band because he was so loud.
My Grandmother had a beautiful Victrola with a sensational flowered horn. I thought I had dibs on it, but my cousin sold it out from under me. I did get her 1928 Mason & Hamblin Parlor Grand so I suppose I can't complain.......not.
