Jean Langlais composed a powerful piece on the well-known theme of Te Deum. It is entitled as 'Hymne d'Actions de grâces Te Deum' and is the third piece of the 'Trois paraphrases grégoriennes'.
Apparently, this piece was rarely played in CB, so I'm all the more pleased to be contributing this impressive piece. I played it on the beautiful sample set of the famous Cavaillé-Coll organ in St. Etienne de Caen.
