News from the nation's capital: Deborah Rutter, one of the most capable leaders in the perennially fraught orchestra business, is leaving her post at the Chicago Symphony in order to become the president of the Kennedy Center. The institution is a peculiar and problematic one, and Rutter will have her work cut out for her. She seems, however, an excellent choice. La Scala, meanwhile, has announced that Riccardo Chailly is to be its next music director. This, too, seems a wise move, although at La Scala one never knows what lies in store.
