This Veterans Day marks the 95th anniversary of the end of WWI, the “War to End All Wars.” It also marks the start of a months-long commemoration of The Great War, beginning with the Cincinnati Opera’s presentation of the Cantus Vocal Ensemble performing “All is Calm: The Christmas Truce of 1914.” Opera Director Evans Mirageas, who conceived the commemorative effort, discusses the inspiration for his idea, and the exhibitions and performances involved.
