SSO Chorus at Carnegie Hall

The SSO Chorus took part in a Presidents' Day performance of the Mozart Requiem. Our singers and VIP guests paid their own way to get there! The concert was fantastic - We will receive a copy of an archival DVD, and plan to have a "viewing party" (Date and time TBA) and we hope to return for another event perhaps next year! If you would like to help us, please donate today!
