This is my entry for Week 102 of the Contest.
I'm playing "Preambule" from "24 Pieces en style libre" by Louis Vierne.
The sample set is the newly-released Sankt Arnual, Saarbrücken instrument (Kuhn, 1995) from ForestPipes. The organ itself is built in the French symphonic style, so it is ideally suited to the music of Vierne.
