At the center of this production are three of the most extended chorale fantasias of the North German Baroque, which superbly showcase the richness of sound of the Schnitger organ in Stade. Reincken's fantasies have survived only through the enthusiasm of the young Johann Sebastian Bach, who improvised on the same chorale for half an hour during a personal meeting with the aged master - years after he had made a copy of the latter's fantasy on An Wasserflüssen Babylon. In addition, organ works by Buxtehude and vocal works by Tunder will be heard.
