Bach: Orgelbuchlein, BWV 599-644 [2 CDs]

With it's forty-five chorale preludes, the Orgelbüchlein bears witness to a mastery of the art of improvisation on the organ, as the congregation heard it at the time before singing the hymn in it's turn. By collaborating with the combined forces of the Ensemble Vocal Bergamasque, Benjamin Alard gives the 'little organ book' it's full significance and expressive power. (Harmonia Mundi)
