21st Century Consort's 'Pierrot Lunaire' lacked only an audience

One of the most influential works of modern music celebrated its centenary this season. Arnold Schoenberg's "Pierrot Lunaire," an unforgettable atonal song cycle that premiered in October 1912, shattered conventions about how composers treat the human voice. The 21st Century Consort marked the occasion with a performance of the work Saturday at the Smithsonian American Art Museum, for a regrettably small audience.
