Opera Idaho General Director Mark Junkert will discuss and give video and audio examples of the operas of Giacomo Puccini, with special emphasis on Tosca, which Opera Idaho will perform in a semi-staged version on Feb. 18 at Presbyterian Church of the Bigwood, Ketchum. Other operas considered will include Madama Butterfly and La bohème, which along with Tosca are three of the top ten most performed operas annually, and lesser-known operas such as Turandot, La fanciulla del West and La rondine.
