„Anna Amalia, Princess of Prussia wrote a sonata for Flauto dolce and B.C. which is highly virtuoso music yet extremely rich in content. Maria Loos demanded everything from her soprano recorder. She remained completely relaxed however; playing the recorder and her air of merriment seem to be her specific expressions of life. The way she and the cellist observed one another secretly before the entry into the allegro was worth seeing.“
