He produced himself area of the post-war reawakening of Breton ethnic identity. His history of peasant lifestyle and his participation in the Cercle Celtique or Celtic Cultural Association of Poullaouen led him to the thought of creating a fresh kind of event for Breton music and dance. It might be just like the community-based fest-noz, or evening party, except that it could bring people jointly from various areas of Brittany.
