A fiery prima donna is forced to play a role she never imagined when she becomes trapped between her allegiance to her rebel lover and the scheming of a treacherous police chief who will stop at nothing in his lust for her. The explosive triangle comes to a hair-raising conclusion in one of opera's bloodiest, most intense dramas. One of the most popular of all operas, Tosca is a passionate tale set to some of Puccini's most openly beautiful and passionate music. Placido Domingo conducts. Saturday, August 24, 1 to 4 pm.
