The vocal harmonies and rich repertoire of the Goadeg sisters -- Maryvonne, Thasie, and Eugenie -- helped to make Les Soeurs Goadeg one of Brittany's most influential traditional singing groups. Taught kan la diskan, a style of singing popular in the Lowlands of Brittany, by their parents, the three sisters first attracted attention in the 1920s, '30s, and '40s. Reuniting in 1956, after a decade-long hiatus, the sisters continued to perform at music festivals in their homeland until Mayvonne's death in 1983. Thasie died 15 years later. In 1994, Eugenie was persuaded, by her daughter, Louise Ebrel, to return to music as a soloist. She recorded a solo album, Gwirziou, the same year. Breton harper Alan Stivell served as les Soeurs Goadeg's primary accompanist, although, the trio was occasionally accompanied by other Breton musicians including the Leprecahns, Rene Wermeer, and Happy Traum.
