The Rite of Spring
"A certain part of the audience was thrilled by what it considered to be a blasphemous attempt to destroy  music as an art, and, swept away with wrath, began very soon after the rise of the curtain, to make cat-calls and to offer audible suggestions as to how the performance should proceed. The orchestra played unheard, except occasionally when a slight lull occurred. The young man seated behind me in the box stood up during the course of the ballet to enable himself to see more clearly. The intense excitement under which he was labouring betrayed itself presently when he began to beat rhythmically on top of my head with his fists. My emotion was so great that I did not feel the blows for some time".
