Composed not for church services but for private patrons, Johann Sebastian Bach’s motets are highly individual and diverse works that telescope the entire range of Baroque choral music into a small, concise form—from multiple voices interwoven in intricate counterpoint to chorale-style singing. With their complete recording of the six motets, Cantus Cölln and its musical director Konrad Junghänel have set a standard rarely equaled over the past 20 years. Joined by an instrumental ensemble, the singers now present the complete cycle of these works at the Pierre Boulez Saal.
