There are indeed Festou Noz in Brittany every weekend in the summer. Just look out for the posters. Not all will be the pure drop of traditional music but all are fun, and the best are not really for tourists but for locals to have a good old dance.

If it is the pure drop you are after, why not try the competitions for musicians and dancers that take place in August leading up to the All-Brittany finals at the Chateau de Tronjoly, Gourin on 6 September?

A personal favourite is the Festival du Dans Plinn (a round dance specific to that specific area of Brittany). This takes place on 15 August in the charming spot of Danouet near Bourbriac. There are competitions of sonneurs de couple (the ultra- traditional Basse-Bretagne combination of bombarde and biniou) and also between dancers to see who can do the plinn best. It makes for a great day for anyone interested in Breton traditional music and there is a fab fest-noz in the evening.

Another similar festival, this time of the Dans Fisel, takes place later in the month at Rostrenen (usually around the 31 August).

Another great one is Gallesie en Fete at the end of June at Monterfil. More music and dancing, this time mostly of 'Haute', or east, Bretagne, the Gallo-speaking area. Also traditional sports and games.
