La Valse
Maurice Ravel was 31 when he began writing a piece that he called simply, "La Valse," a light tribute to carefree Viennese waltzes. He set the piece aside, then saw the agony of World War I firsthand. When the 45-year-old Ravel came back to his waltz, the world was different place. He was a different man. And La Valse was no longer a light tribute. In 13 minutes, you can hear the waltz slowly go delirious, spin out of control, and finally, fly apart into chaos.
