Each year, first week-end of June, Osismi Speied Band organises a festival named "Faites de la montagne".

The main purpose is the organisation of a duo competition named "sonneurs de couple" in Brittany. Musicians make use of Bombarde and Scottish or Breton bagpipe to play tunes from "Montagne" historical area.

Competitions take place outside in presbytery garden and Town Hall square (Inside if it is raining). A wood floor  is installed on the square to allow dancers to have some "Gavotte". They even can take part into the dance competition.

Competitions are also opened to accordionists (Le Schelton Bar), clarinettists (Ty Koz Bar), traditionnal singers (during dance competition), and "Free Duo".

The day's organisation is the following :

Morning : March - Melody for "Sonneurs de couple"

From 14h : Gavotte dance competition for Sonneurs, Singers, and
Dancers on Town Hall Square
