Skandalkonzert

Operetta composer Oscar Straus, a witness to the alleged assault, testified that the slap had been "the most harmonious sound of the evening."

[1] Though not present at the concert, he was granted leave to attend the dress-rehearsal that morning, and three days later he wrote a prose sketch depicting Alma Mahler there.

[1] For Berg's work the Skandalkonzert had lasting consequences: the songs were not performed again until 1952, and the full score did not appear in print until 1966.

[3] The first performance of Schoenberg's Gurrelieder was held on 23 February 1913, in the Great Hall of the Musikverein, under the direction of Franz Schreker, and was an overwhelming success.

[4] Press reports from the period mention tumultuous riots: Schoenberg's followers and a student of his and opponents yelling at each other, throwing things, disturbing the performance, destroying furniture, etc.
