This book examines the impact of the Canadian Broadcasting Corporation/Societe Radio Canada (CBC/SRC) on the development of art music in Canada during the broadcaster’s first fifty years (1936-1986). In so doing, it investigates the achievement of one man: John Peter Lee Roberts. Born in Australia, he arrived in Canada in 1955, and, over the next thirty years, he worked tirelessly as a producer, administrator and adviser at the state broadcaster to bring the music of Canada to the world and the world of music to Canadians. Roberts also played a crucially important role in commissioning, disseminating and promoting new music by Canadian composers.
