Ferenc Erkel: Bánk Bán [Import]

The plot, in a nutshell:
András II (13th century), the king of Hungary, is away in the crusades. The country is under the rule, meanwhile, of his non-Hungarian wife, Gertrud, savaging the country by her vast foreign company. She cares nothing for the country or the people, and allows some very unsavory characters in the royal court, like the evil Biberach and her lust-filled brother, Otto, who wants to seduce the wife (Melinda) of one of the country's most powerful and noble counts (Bánk), who is currently traveling on the king's business, thus leaving his wife at the court. The queen allows Otto to drug and rape Melinda. Bánk is summoned by Petur, an other count, who is so distraught over the country's affairs that he plans to dispose the queen. Bánk, although first outraged that a fellow noble would plan treason, becomes concerned when Biberach hints that Melinda is in trouble. Biberach tells Bánk where to be and when, and Bánk spies Otto kissing his wife, though he fails to see her struggling against him. He is outraged, and decides to tell Gertrud of the rebel's plot, but to take action himself if she does not try to help the country. He confronts Melinda, but forgives her when realizes her innocence. Nevertheless, Melinda slowly becomes insane over the fact that she, unwillingly though, was with another man. Bánk also meets with a poor peasant who tells him of the immense poverty and misery in the country. Bánk recognizes him as Tiborc, who saved his life from an assassin many years ago. He entrusts Melinda and his son to Tiborc and leaves to confront the queen. At the court, he tells her of all the troubles, but she insults him and brushes off his complaints. He presses the issue, and she pulls a dagger. In the scuffle, she is stabbed and dies. Biberach and Otto escape.
In the final scene, András returns to find his wife dead. After a short investigation, it turns out that she was killed by his most loyal subject, Bánk. The grieving king tells him to draw his sword, initiating a duel, but just then, Tiborc enters the hall with the bodies of Melinda and her son. Melinda took her life during a storm, unable to deal with the sinful world. Bánk collapses.

All in all, the finest opera to grace any stage in the world. A must-have for everyone.
