L'incoronazione di Poppea
At the Teatro Colón she was heard between 1915 and 1940, creating the title part in the world première of Respighi's "Maria Egiziaca" in 1934, as well as several operas by Argentine composers. She sang over 70 rôles ranging from Ottavia in Monteverdi's 17th century opera "L'incoronazione di Poppea" to works by then living composers.
