At home - open workshop for music in the refugee home Adlerstr., Dortmund, in the period from October 2015 to January 2016 on behalf of the Landesmusikrat NRW. The intention was to create a musical "castle in the air", that means, to play integrative free music with refugees. This music should restore their energy and serve as a resource. Free Music was black music, which mingles in Europe with classics and new music. In the center of the workshop were the drums and the viola/violins. On one hand, music could be a universal language, on the other hand it is the "healing force of the universe" (Albert Ayler).
