SERGEY TANEYEV: ORESTEIA 2013, Sosnoff Theater, SummerScape Russian composer Sergey Taneyev’s extraordinary and unjustly neglected opera, premiered in 1895, conveys the searing drama of Aeschylus’ powerful trilogy about the cursed House of Atreus—from Agamemnon’s fateful return from Troy to the trial of his son Orestes. The Bard SummerScape production, directed by Thaddeus Strassberger, is sung by a largely Russian cast with the Bard Festival Chorale and accompanied by the American Symphony Orchestra, led by Maestro Leon Botstein.
