I know this is a bit late, but I had a lot on my mind. Anyway, Tosca takes place in Rome during the Napoleonic Invasion of Italy in 1800. It is known for depictions of murder, torture, and suicide, and tells the tale of a painter who secretly supports Napoleon (thinking that he will institute a republic in Rome), attempting to hide one of Napoleon’s supporters (who escaped from prison) from the authorities while avoiding the suspicions of his lover, Tosca, who believes him to be unfaithful for reasons that won’t go into. It is an extremely dark opera, where every major character dies, onscreen or offscreen, and the protagonists almost completely fail. It was still an interesting show, however. To my untrained ear, each and every singer sounded extremely talented, though an opera connoisseur might be able to prove otherwise. I was very entertained, overall.
