Ermione (2009)

"Ermione is Rossini’s darkest, angriest opera. It was such a resounding flop at its premiere that after its initial run Rossini withdrew it entirely. It takes place in the aftermath of the Trojan War. Pirro, engaged to Ermione, has fallen in love with Andromaca, widow of Hector, who he is holding prisoner, and so forsakes Ermione. Oreste loves Ermione, who only wants Pirro. Pirro asks Andromaca to marry him and she falsely agrees in order to save the life of her son. Ermione, enraged and mad as a hatter, demands that Oreste kill Pirro. He does so, and when he shows her the bloody dagger, she regrets her decision, blames Oreste, goes even madder, and calls down the Furies upon him. Near hysteria, he is whisked away by his compatriots. Everyone is unhappy. There is almost no denying that the work is a masterpiece." (classicstoday.com)
