Charles-Alexandre Fessy - Grand Prélude - L'Organiste Français.
Sample set of Saint Omer.
This more "serious" piece of Fessy is found in the 6th livraison, 11th year of the publication "L'Organiste Français", of which I have several examples in my very small collection of original scores. There are in addition some other interesting works from my collection I hope to share at some point in the future.
