On November 18, 1846, he performed at the Howard Athenaeum in Boston, where he played Il Campanello and Carnival of Venice.
"Le Stregghe" is one of his best examples in which his unique ability to create such lively, almost cinematographic effects is achieved.
Sivori understood that he was the only violinist alive (in the late 1800s) who could immortalize Paganini's art of violin playing and unique Operatic interpretations.
He owned many valuable instruments, including violins by Amati, Antonio Stradivari, Carlo Bergonzi, Gaetano Chiocchi, and Jean-Baptiste Vuillaume.
Although Sivori played it many times as a duo with Bottesini, the version for violin and double bass, had been made much earlier.
