About the musicians.


The chorus for Bach Cantata Vespers is a volunteer choir, with the Grace Church Parish Choir at its core. Other friends of Grace Church audition with the Grace Cantor for a place in the chorus. The Parish Choir maintains a busy schedule, singing for weekly services, festivals, and monthly Bach Cantata Vespers services.

Chorus Roster


The orchestra is an ensemble of dedicated professionals who rehearse and perform together for Bach Cantata Vespers services and other occasional concerts at Grace. Orchestra members play in other local ensembles, teach in local schools, and maintain private studios. Several members of the orchestra are also members of Grace Lutheran Church.
