The OSM, in the company of former winners of the “Cégeps en spectacle” competition, is marking the 50th anniversary of Cegeps with a festive event rich in song, humor, dance – and classical music! An opportunity to hear and admire Koriass, Vincent Vallières, Yann Perreau, Philippe Brach, Charles Richard-Hamelin, Catherine Major, Claudine Mercier and Jessica Viau all on the same stage.
