In 1976, multi-instrumentalist sisters Kate & Anna McGarrigle emerged on the international music scene with their blend of folk-rock and vocal harmonies added to self-penned songs in English and French, many of the latter co-written with Swiss-born poet Philippe Tatartcheff. The 1970s also saw roots performers like La Bottine Souriante gain critical and commercial acclaim within Quebec. Jim Corcoran and Bertrand Gosselin released "La tête en gigue", an influential album that helped bring Quebec roots to crossover audiences across Canada, the United States and Europe.
