It’s a pairing as natural as wine and cheese: contemporaries Claude Debussy and Maurice Ravel. In this program Debussy’s La mer demonstrates that the Impressionist movement was not limited to paintings; his soft musical brushstrokes create sketches of the sea. Meanwhile, Ravel’s popular “Left Hand” Concerto—written for a World War I veteran who lost his right arm—shows off its moody, jazz-inspired rhythm and harmonies.
