Although he only recorded one album (1965), he acquired a solid reputation in the Quebec City area through frequent contributions as a radio host or performer. In 1958, he hosted “Les Créations de Québec,” a CHRC program devoted to emerging talents and their music. Delisle also played an important role in the creation of Association des Auteurs-Compositeurs du Québec.
Marius Delisle achieved popular success with a single song, À Québec au clair de lune, released in 1959. This song was incorporated in the soundtrack of Robert Lepage’s 2003 film La face cachée de la lune.
