“Let's pass over the queue of appearence to express all the admiration for Agnes Zwierko, Neris delicate and compassioned, moderated in her interpretation, magnificent in singing.”

"Without discussion just Agnes Zwierko is the real heroine of this tragedy. She has created the figure of Kostelnicka singing with her strong, convincing and rich voice, full of drama and empatic force, with great and unexpected professionality.”
