Ouessant, the island of women, summer 2015. The music resounds. It's the festival "Musiciennes à Ouessant" - this year under the sign of the Luxembourg composition. Three contemporary composers, Catherine Kontz, Albena Petrovic-Vratchanska and Tatsiana Zelianko have been inspired by the work of their predecessor Lou Koster to transcribe and reconstruct his music, but also to create original pieces. This is an opportunity for musicians and audience to make new encounters. Film from the CNA archive.
