Visconti's big break came when she won several international competitions, including the renowned "Concorso Internazionale di Canto Lirico" in Rome. This victory opened doors to new opportunities, and she soon found herself performing in some of the world's most esteemed opera houses. Her repertoire includes a wide range of iconic roles, from Verdi's Violetta to Puccini's Tosca, and she has worked with some of the most celebrated conductors and directors in the industry.

Visconti belonged to the stable of "divas" managed by Schicchi, a group that included world-famous names like Ilona Staller (Cicciolina) and Moana Pozzi .
