The Rochester Oratorio Society, founded in 1945, is the leading choral/orchestral ensemble in Rochester, New York, and the surrounding seven-county region. The mission of ROS is to produce live choral music of the highest quality, engaging and educating our community in numerous musical genres, and gratifying our volunteer singers with the professionalism of their art. Led by Maestro Eric Townell since 2006, the Rochester Oratorio Society gives voice to the very best qualities of Rochester and western New York.Comprising approximately 145 auditioned, adult members in a typical performance season, the ROS presents two to four performances of predominantly well-known masterworks for chorus and orchestra from the 18th-20th centuries. In this role, the ROS has offered the local premieres of monumental works, such as the Berlioz Requiem and Britten's War Requiem, and many performances of Handel's Messiah, under the direction of founder Theodore Hollenbach and successors Roger Wilhelm and Eric Townell.
