Sorge's choral prelude to "Herr Jesu Christ, mein Lebenslicht" is again a charming piece. The introduction has two voices on the accompanying manual. After the choral melody enters, the accompiment reverts to one voice. The texture of the piece is therefore tio-like throughout. With very little means Sorge creates a piece that sticks to the mind.
The recording was done with the Hauptwerk software and the sample set, made by Voxus, of the Van Dam organ (1832) in Tholen (http://www.voxusorgans.com/en/tholen).
