Tosca Rousseau

Tosca Rousseau is a unique and exciting up-and-coming soprano. A breath of fresh air, Tosca’s path to a professional singing career looks slightly different than most of her peers. At sixteen years old, Tosca met her teacher Anna Catarci who encouraged Tosca to study singing technique privately and pursue a career in Opera. 

Five years later, in 2017, Tosca followed her passion for the Baroque repertoire and began studying with Guillemette Laurens. Tosca developed her voice, with Guillemette, into a full-bodied sound that glides through coloratura effortlessly. Armed with vocal agility and a vibrant, pliable tone, Tosca is enjoying the Baroque and renaissance repertoire in the early stages of her career.

Tosca’s first experience singing in an opera was a semi-staged production of Monteverdi’s L’incoronazione di Poppea at the Festival Saint-Bertrand de Comminges, in which she played the title role. From this, she was hooked and would return to the festival the following year to play Cephise and Roxane in Campras’ L’Europe Galante. Tosca then made her on-stage operatic debut in 2019 as ‘Gilda’ in Verdi’s hit opera Rigoletto at the Teatro Lirico di Magenta in Milan.

Since then, Tosca has contributed to bringing unknown and forgotten works back to audiences. These works include La Belle au bois dormant by Guy de Lioncourt (La Princesse Aurore) and Paul et Virginie by Victor Massé (Virginie), all of which she performed in Paris.

Tosca’s success on the competition platform has been an exciting stepping stone to roles for the singer. She won the 73rd edition of the ‘Concorso Lirico Sperimentale A. Belli di Spoleto’ and made her young artist debut as Berta in Rossinis’ Barbiere di Siviglia under the direction of Paolo Rossi. For her second year as a Young Artist in the 74th edition she played Serpina in Pergolesi’s La Serva padrona as well as Corilla in Francesco Gnecco’s La Prova di un’opera seria (1802). Other roles include; Donna Elvira (Don Giovanni) Mozart and Télaïre (Castor et Pollux) J.P. Rameau, which was televised on national television.

Most impressively, Tosca (whilst singing Télaïre in Castor et Pollux) learned and jumped into the title role in Lully’s Armide. Tosca enjoyed the challenge of learning this terrific role in a time crunch and thrived in the experience of singing at the Warsaw Chamber Opera under conductor Benjamin Bayl and Director Deda Cristina Colonna.

On the concert platform, Tosca has been fortunate to sing solo recitals at the Les Passions de Montauban Festival (2019 and 2020) and Fermo Vocal Fest (2022). 


Tosca is thrilled to be studying under a new teacher, Alessandro Luciano in Rome. In addition, she is excited to be working with Robert Mirshak at Mirshak Artists Management and is looking forward to seeing how this relationship shapes her career.
