Experimentation of some BACH at ST-Ouen (Prelude and fugue BWV 543, choral Wachet auf)

Prelude BWV 543 at 0:00
Fugue BWV 543 at 3:44
Choral BWV 645 at 10:19

This is a trial to make some Bach emigrate from Germany to St-Ouen, which is not exactly a Bach-organ (although Dr Schweizer, Widor's pupil, wrote that a genuine Cavaillé-Coll was the most perfect organ to play Bach).

There were three basic options to do so :
1. To try to mimic a 18th thuringian organ played by a 18th thuringian guy (rather, as we imagine 18th thuringian guys played).
2. To try mimic a late 19th-early 20th french guy playing Bach on a Cavaillé. There are more liable sources about this (Vierne's recordings, Widor's and Schweizer's texts included in their common Bach's edition, Dupré's edition...).
3. To let the organ take the lead, any consideration of historicity or "authenticity" being put apart.

N°3 was selected, even if the result may appear as most questionable.

In the fugue, there are some REC reeds pulled out from the beginning, so as to make the medium voices more audible, as the medium is rather restrained in Cavaillé's flue stops.
In the choral, the right hand uses all the 8' and 4' strings of the organ coupled, the left hand using the trompette from the Bombarde division.
