"Elvira (Soprano), sung by Marie-Audrey Schatz, had perhaps the most difficult part of the evening. Her clear voice, very understandable, showed her intense jealousy, tension and frustration towards Giovanni. At times employing forceful text delivery, following the emotions, she rose to the challenge and mastered her arias perfectly, very much to the pleasure of the audience”, wrote Das Opernmagazin.

In 2020 in Cologne, she sang the role of Tochter in the world premiere of ELEONORE- Ich muss nicht glücklich sein by Gordon Kampe, Oxana Omelchuk and Vincent von Schlippenbach.

"And at the end, when Marie-Audrey Schatz (Beauty) indeed  renounces the earthly pleasures and almost in a whisper, with the most delicate piano tones, commits herself to the truth and the virtue, it is as quit as a mouse in the monastery yard.  Finally it is not Time and Truth that triumph, but Beauty - especially the beauty of the voices.", wrote The Märkische Oderzeitung,
