Chorale trio "Der du bist drei in Einigkeit"

Christian David Graff worked as organist at Kirche St. Ulrich und Levin in Magdeburg from 1719 until his death in 1774. He was a pupil of Johann Bernhard Bach (a cousin of J.S. Bach). In the past Graff was considered a pupil from J.S. Bach, but that isn't true, probably the cause of a confusion between J.S. and J.B. Bach.

Christian David Graff was organist of Schnitger organ in Magdeburg. So it's nice to record this piece on an early North German organ model.
