Metropolitan Opera

The provided articles do not directly mention the Metropolitan Opera. One article discusses the relationship between Frida Kahlo and Diego Rivera, focusing on a novel about them being adapted into a Netflix series. The other article reports on the auction of a stage set designed by Salvador Dalí. Neither article provides any information about the Metropolitan Opera, its activities, or its current relevance. Therefore, it is impossible to create a summary about the Metropolitan Opera based solely on these two articles.
