This ad from the March 9, 1931 Simpson's Leader-Times (Kittanning, PA) is in no way subtle. The consequences of using recorded music at theatre performances rather than live musicians are, "Monotony in the theatre - corruption of taste - destruction of art." Yikes.

Monotony in the theatre - corruption of taste - destruction of art. These must inevitably follow substitution of mechanical music for living music.
