On 3 October 1990, the union of the two German states was officially declared. The document that constitutes the Federal Republic of Germany is the Grundgesetz (Basic Law). Its precursor can be found in the Weimar constitution passed in 1919. Polish director and re-discoverer of the choral principle Marta Górnicka is staging the Basic Law in front of the Brandenburg Gate as part of the Day of German Unity 2018 in Berlin, with a chorus of 50 professional and non-professional actors from civil society’s many different spectra. In her Workshop during WAR OR PEACE, she continues her work with the document and provides insights into playing technics of the chorus piece.
