Tosca, Staatsoper Stuttgart, May 2014
"Maria José Siri as Tosca was a discovery for me ... exciting and moving moments ... Particularly her interpretation of the third act scene when Cavaradossi is shot was breathtaking and she touched the hearts of the audience. ... "Vissi d'arte" was sung with extraordinary vocal colours and with a smooth timbre."
Alexander Walther, Der Neue Merker
"... Maria José Siri's remarkable range of vocal colours... . The Uruguayan soprano mastered the emotional surges [of the role] effortlessly and with secure intonation. … her acting was highly present and authentic... ."
Thomas Krazeisen, Esslinger Zeitung
"Maria José Siri's highly authentic interpretation, stage presence and even vocal registers were fascinating... Her pleasantly timbred voice combined even vocal lines, an always well-projected, harmonic, round sound and flexibility even on the high notes... . (…)
With this combination of vocal perfection and intense interpretation she was without doubt the star of the performance."
Udo Klebes, Der Neue Merker
