How to sum up Claude Debussy in just a few words? A man who revolutionized 20th century music. Who broke all the rules for composing. Who said, in fact, that there was only one rule, and that was pleasure. A man who explored musical moods and colors and textures in a way no one ever had before. Today is Claude Debussy's 150th birthday. We'll celebrate with some of his greatest works, including a performance of La Mer from San Francisco.
