We celebrate the 150th anniversary of the death of the great Italian composer Gioachino Rossini with an evening illustrating the wide range of his majestic, hilariously wicked and sparkling music—arias and duets from Tancredi, Adina, Cenerentola, and selections from his brilliant piano music Péchés des vieillesse (Sins of Old Age) composed at the end of his life. The enchanting contralto Emily Marvosh is joined by soprano Sonja Tengblad ("crystalline tone and graceful musicality—Boston Globe) in a romp through vocal works, that will also include the glorious Barcarolle by Jacques Offenbach.
