A popular singer and dedicated advocate of Quebec song, Robidoux was among the first artists to record original Quebec songs, including pieces by Raymond Lévesque in the U.K.’s Decca Studios, in breach of his agreement with RCA Victor, a label that refused to sign Quebec singer-songwriters and preferred releasing adaptations of American or French hit songs instead.

As a radio host, Robidoux played a key role in the promotion of Quebec artists, a cause that was close to his heart. A pioneer of the development of the Quebec music industry, he organized songwriting competitions that led to the discovery of many new artists, including André Lejeune.
