When I was starting my undergraduate degree, sadly I had a strong dislike for all things opera. However, I loved Shostakovich (and still do). Lady MacBeth was the opera that got me listening to and liking opera in general.
It's so full of raw brutality, brooding, beauty, sarcasm, you name it ... I love it, especially if I'm in a bad mood.
I have a recording of the original version of the opera. I've heard a suite of the interludes from Katerina Ismailova, the revised version he did in the '60s, but I haven't heard it in its entirety. Some of the interludes are quite different.
