I will be able to contribute more when you start an LP thread. To the people complaining about the lack of opera recommendations, I have about 150 opera sets. I have listed two below, and an “oratorio” and a dance song cycle. Opera is not dead: these are 20th century works. The clip of the performance of the Adams opera is outstanding.
For now, I recommend
