This is the twin prelude to a piece I uploaded almost two years ago. It uses just the first two phrases of the choral melody. But Kauffmann has them repeated.
The recording was done on the sample set of the Müller-organ in the Sint Bavokerk in Haarlem by Voxus Organs for Hauptwerk.
HW: Octaaf 8′, Octaaf 4′
Kauffmann, Christ lag in Todesbanden
