Established in 1876, The Boston Cecilia is a group of select musicians that performs a broad repertoire of choral works with historical sensitivity as a guiding principle. Cecilia continues a rich tradition of premieres, groundbreaking period instrument productions, and masterpiece performances through its concerts. The Boston Cecilia and All Saints have enjoyed a special relationship since 1969, and the chorus performs here at least twice a year, including its traditional Christmas concert each season.
