The first public performance of the noise orchestra took place on 21 April 1914 at the Teatro dal Verme in Milan. According to Russolo, the audience of conservative critics and musicians came only “so that they could refuse to listen.” As soon as the orchestra began to play, the crowd broke into a violent uproar. The musicians continued undaunted while fellow Futurists hurled themselves into the audience and defended the Art of Noises with their fists. In the end, eleven people were sent to the hospital, none of them Futurists, as belligerence was a central component of the Futurist approach to art and life, and many were talented boxers.
