 Music was the least restricted of cultural activities , probably because Hans Frank regarded himself as a fan of serious music . In time , he ordered the creation of the Orchestra and Symphony of the General Government in its capital , Kraków . Numerous musical performances were permitted in <unk> and churches , and the Polish underground chose to boycott only the propagandist operas . Visual artists , including painters and <unk> , were compelled to register with the German government ; but their work was generally <unk> by the underground , unless it conveyed propagandist themes . <unk> museums were replaced by occasional art exhibitions that frequently conveyed propagandist themes .
