For some main house productions - like The Minotaur - the prices will be the same as they were at their previous showing. For others - only Tosca and La bohème are mentioned - prices will be lower than they were before. (The price drop will apply to all tickets, top to bottom.) And for high-demand productions such as The Ring, Don Carlo, La Rondine and Nabucco, prices will be higher.
