The Goadec Sisters (Ar C'hoarezed Goadeg in Breton) usually known as Les sœurs Goadec in French, was a Breton singer group originating from Treffrin (Côtes d'Armor, France). The trio represent the traditional music of Brittany, singing a cappella. The three sisters were Maryvonne (1900-1983), Eugenie (1909-2003) and Anastasie Goadec (1913-1998). They began to animate fest-noz (night festival) in 1956, among the pipers and bombard players. Accompanied until 1964 by their two sisters, Louise (1903-1964) and Ernestine (1911-1964), their repertoire consists mainly of laments (Gwerzioù in Breton). As a trio, they attempted to integrate the song to dance and adapted the technique of repetition (kan ha diskan).
The Breton revival, the wave Pop Celtic and the popularity of Folk music propelled them in 1972 and 1973 on to the front of the stage, following Alan Stivell, one of their biggest admirers. The three sisters brought a lot to the Breton culture and its sustainability. Several recordings allowed to transmit the vast repertoire of songs and techniques specific to Breton folk songs.
Annie Ebrel is a second cousin of Louise Ebrel, who is a daughter of Eugénie Goadec.
