On April 30 the world celebrates International Jazz Day, a UNESCO designation to honor an art form that has brought people and cultures together from all over the world. The beautiful mural we highlight today epitomizes the wondrous alchemy that is jazz. Even its location—the junction of the North Beach, Chinatown, and Barbary Coast neighborhoods in San Francisco—symbolizes a dynamic nexus of heritage and experience galvanized by a musical form that has unleashed creative genius for more than a century.
