Excerpts from Books and Wikipedia
"The score was so complex that it required 100 rehearsals and the premiere had to be delayed for a year. When it opened on May 29, a veritable riot resulted. The discarded music and the savage story of crude pagan peasants sacrificing a maiden to greet the renewal of spring outraged even the sophisticated Parisian audience, whose yells and catcalls escalated to fully fledged fistfights. The riot drowned out the music, Stravinsky stormed from the theater, and the performance ended in chaos." [Furtado: 1001 Days]
