The Ensemble Gilles Binchois, founded in 1979, bears the hallmark of a group dedicated to the discovery and interpretation of music from the Middle Ages. Unaffected by fads or fashions, the group has remained completely loyal to its objectives, which include close study of the various repertoires (especially French) and of their relationship with music of the oral tradition, study of different types of notation, and an attempt to achieve the vocal and instrumental sonorities appropriate to these repertoires.
