Marcel Dupré wrote his Vingt-Quatre Inventions pour orgue Op. 50 in 1956. This consists of 24 fine and inspirational small works that I think are real gems. They are dedicated à la memoir du Marcel Samuel-Rousseau who was a French composer, organist, and opera director and contemporary of Dupré.
This is the last one that I will upload so far. I hope to be able to find some time in future to upload more of these nice pieces.
