Rossini’s perfectly honed treasure survived a famously disastrous opening night to become what may be the world’s most popular comic opera. The opera offers superb opportunities for all the vocalists, exciting ensemble composition, and a natural flair for breezy comedy that has scarcely been equaled since. Times: Friday 7:30 p.m. Saturday 2:00 p.m. and 7:30 p.m. Sunday 2:00 p.m.
