The California Bach Society, a 30-voice chamber chorus, has established a reputation for its interpretations of Renaissance and Baroque choral music. Specializing in historically informed performances since 1998, the choir has shared the stage with such Early Music luminaries as Magnificat and members of the Philharmonia Baroque Orchestra, and was a featured concert presenter at the 2000 Berkeley Early Music Festival.

The appointment of artistic Director Dr. Paul Flight in 2006 has resulted in four highly successful concert seasons. A fine voice coach, Dr. Flight has attracted talented new singers, and his sensitive direction has brought new definition to the choir. A recent reviewer from San Francisco Classical Voice wrote "Flight has made of the choral group a professional ensemble capable of every expressive nuance and glorious ensemble sound." Dr. Flight has enthralled audiences and critics with his thoughtful and refreshing programming, eliciting reviews such as "one of the most delightful programs of Christmas music in my memory".
