To many in the audience sitting in the Champs-Elysees Theater in Paris, what unfolded before them was ghastly, unthinkable, an affront to the senses. Like finding that someone laced your ice cream with jalapeno peppers. Noses wrinkled, ears prickled, and eventually, fists started flying. It was the premiere of the most revolutionary piece of music of the 20th century, Igor Stravinsky's "Rite of Spring." This year marks the centennial of the ballet. We'll revisit that day in Paris 100 years ago, and the riot that ensued. And we'll hear a peaceful performance from New York City.
