Tchaikovsky’s opera “Eugene Onegin,” which opened the season at the Metropolitan Opera, will launch the 2013-14 series of live HD performances at Guild Hall on Saturday at 1 p.m. Anna Netrebko and Mariusz Kwiecien star as the love-struck Tatiana and the imperious Onegin in Tchaikovsky’s fateful romance. Deborah Warner’s new production, set in the late 19th century, moves episodically from farmhouse to ballroom, with a powerful snowstorm providing the dramatic setting for the finale. The Russian maestro Valery Gergiev conducts.
