Swan Lake is beloved for good reason. There’s something irrefutably wonderful about Tchaikovsky’s romantic score combined with Marius Petipa and Lev Ivanov’s choreography, which capitalizes on the natural synergy between the lines and forms of classical ballet and the movement of swans. The esteemed Russian Grand Ballet is bringing its production of the classic to the Palace of Fine Arts (home to a few locally famous swans of its own) for one night only.
