Silvy,
Ferri has danced in one classical role that I know of: Nikiya in LA BAYADERE opposite Julio Bocca. If I'm wrong about this, please someone chime in, but Ferri isn't known as a strong classical dancer. To my knowledge she has never danced SWAN LAKE, SLEEPING BEAUTY, RAYMONDA because she doesn't have the formidable technique required for these ballets. She excels in dramatic roles like MacMillan's Juliet and Manon.
