This organ is a copy, a perfect one. So, why not interpret excellent pastiches in the style of Bach, Böhm, Buxtehude ?
the Swiss composer Nicolas Wolleb gives a perfect demonstration of this art of understanding how the young JS Bach learned, studying and copying his masters.
I'm not sure that the score is free from faults, but I play it how it's published.
1. Praeludium pedaliter in g
2. partita "Wer nur den lieben Gott"
