In 1913 the Paris premiere of Igor Stravinsky's revolutionary score for Le Sacre du printemps (The Rite of Spring) by Sergei Diaghilev's Ballets Russes caused a riot (literally). Stravinsky's shockingly brutal yet rivetingly beautiful score changed the course of 20th-century Western music. Today Ken over at Down With Tyranny has the fascinating story of how America got introduced to this incredible music via Walt Disney's Fantasia.
