Hainaut Belles bretelles

The Hainaut Belles Bretelles Festival is held every year around Pentecost in Hergnies, northern France, organized by the Club Léo Lagrange. Over three days, around twenty bands and artists perform music built around the accordion in all its forms, from musette to rock'n'roll, klezmer, cajun and folk. All concerts are completely free, in a spirit of conviviality and openness, rounded out by a nature walk and race.
