The Grencsó Free's Group is an experimental formation of István Grencsó with talented young people, formed on the occasions of the Adyton Creative Community in Nagymaros. They balance in a special way with the possibilities offered by composed and spontaneous music solutions. A collective collaboration of three generations that attempts to reinterpret Grencso’s compositions. "Sometimes the music of Eskimos and extinct nations can be seen in our music," István Grencsó jokingly points to the difficult contours of their music. We can hear them on the Opus stage for the first time this evening.
