Pre-concert Talk with Alexander Platt and Tania Leon.  The Cassatt String Quartet has performed across the world to critical acclaim since its founding in 1985.  Ursula Oppens, a legend among American pianists, is widely admired particularly for her original and perceptive readings of new music, but also for her knowing interpretations of the standard repertoire. Tania León (b. Havana, Cuba) is highly regarded as a composer, conductor, educator, and advisor to arts organizations.
