Awesome Clip from Shosty's Katerina Ismailova

For those who do not know this great opera by Shostakovitch, I thought I would share this clip that I stumbled upon from Katerina Ismailova. Katerina is the epitome of the traditional Russian trophy wife. Ignorant and bored out of her mind, she feels trapped and desperate for real affection in her loveless marriage to Zinovy. That's where Sergei comes in. He's the farm hand who got fired for sleeping with his last boss's wife (you can assume what kind of character this playa playa is).
In this particular scene Sergei is paying a late night visit to Katerina under the nose of her father-in-law Boris and while her husband is away on a business trip. He asks for a book but obviously his real intentions are less innocent...
Consequently Katerina kills Boris by serving him poisoned mushrooms and later she and Sergei kill her husband when he catches them in the act... yeah that's about the place in the opera where Stalin apparently stormed out of the auditorium in disgust (off to the frozen tundra with Shosty over that one). Then the couple gets caught and sent to Siberia. Sergei dumps Katerina for another labor slave, Katerina loses it, she grabs Sergei's new girlfriend and pulls the both of them to their death by raging/freezing river.
Well, nobody said Russian married life in the old days was easy...
