Beethoven’s Missa Solemnis

During the last 2 months my choir and I have given concerts in the cathedrals of Montreal, Canada, and Lausanne, Switzerland. The Missa Solemnis by Beethoven is considered one of his best works and one of the most important masses of occidental culture (Wikipedia).
The concerts were organized by the Choeur Universitaire Lausanne, the Chœur de l’Université du Québec à Montréal, the Orchestre Symphonique et Universitaire de Lausanne and 4 solists. Roughly 1700 visitors attended the concert in Montreal (see picture).
