Even today, Protestant church music has been strongly characterized by Johann Sebastian Bach. The "musical preacher" allows the listener to understand both emotionally and rationally the theological message entirely in the spirit of Martin Luther. Therefore, it is is fitting that in 2017 the newly released recording of the Gaechinger Cantorey under the direction of Hans-Christoph Rademann reflects the Reformation in full: The cantata Gott, der Herr, ist Sonn und Schild was written for Reformation Day in 1725; the "Lutheran" Mass, BWV 236, musically draws to individual parts of the cantata; and the chorale cantata Erhalt uns, Herr, bei deinem Wort is based on a hymn written by the Reformer.

At the same time, the CD also characterizes the new direction of the Gaechinger Cantorey: for its second CD recording under the direction of Rademann, the choir is accompanied by the Cantorey’s own newly formed baroque orchestra. The CD also features the first recording of a chest organ, commissioned by the Bachakademie, that is a replica from the organ workshop of the legendary Gottfried Silbermann, a contemporary of Bach.
