Peter, Thanks a lot for this information.
I have been to the concert and to the 2 rehearsals before.
Small ensemble (2 Fl, 2 Ob, 4 Vn, 1 Va, 1 Vc, 1 Kb, 1 Bn, Organ,
SATB : 3,2,2,2, ...), but great sound.
Disposition of the orchestra : all basses (Basso, Kb, Vc and Bn) in the center.
Unique experience !
There are now samples of the concert at :
