"The soprano is vocally impeccable and draws a character ... which makes it easy to identify with. In the duet of the first act, her jealousy is adorable. The fear that freezes her and makes her far too submissive, clearly appears in the confrontation with Scarpia. “Vissi d'arte”, the moment in which she finally confronts herself, is sung with touching intensity and got a big round of applause. The high C of the "lama" is bright, very solid and it is approached effortlessly and with ease."

"Maria José Siri is Floria Tosca, the main character... In this role, Siri has become a renowed and established interpreter: once again, her performance does not disappoint. A Tosca that does not exceed and never turns into vulgar scenes, tantrums, or tears while fully reflecting the proverbial jealousy that distinguishes her, albeit in a more mature and controlled manner. An aspect that we consistently find throughout the opera: fear, passion, courage and suffering do emerge, but always with great dignity. Musically speaking, this is reflected in an expressive singing line, which is homogeneous in every register and rich in nuances."

"Maria José Siri, in the title role, has a large and luminous voice, soaring in the high notes... she flawlessly delivers her only solo gem, a "Vissi d'arte" of pure lyrical abandon, as well as the duets with the other two protagonists."

"The Uruguayan soprano outlines a refined, well-constructed and vocally clear Tosca – the sorrowful phrasing of «Vissi d'arte» is praiseworthy..."

"In the title role, Maria José Siri finds a way to emerge, and is appreciated for her clear and luminous voice, with well-dominated centers and powerful, long and sustained high notes ("Io quella lama gli piantai nel cor")... Her great expressiveness in her only aria, which was interpreted with feeling and sensitivity, also needs to be recognized: the audience enthusiastically applauded and asked for an encore. It is a nostalgic, dreamy vision, the one that emerges from her Vissi d'arte: it is in line with her Tosca which, perhaps due to the guidelines of the director, appears cold and detached even in the murder scene (the one that horrified Herr Gustav so much), and it is reflected in the acting performance..."
