Russian novels have a reputation for being thick, and keeping their characters straight in your head is a task. When it comes to Eugene Onegin, the verse novel by Russia's most famous poet, Alexander Pushkin, the outlook is straightforward: Country girl Tatiana has a crush on the dandy Eugene, but he rejects her. When Tatiana grows into a cultivated woman, Eugene tries to seduce her, but it's too late. Pyotr Ilyich Tchaikovsky adapted the story to an opera, Evgeny Onegin, being performed Friday and Sunday, Feb. 13 and 15, at the Egyptian Theatre. The opera will be sung in Russian, but never fear: supertitles will be projected above the stage, and Opera Idaho General Director Mark Junkert will conduct a talk an hour before each staging.
