Virgilio Lazzari was an Italian operatic bass who had an active international performance career from 1908 to 1953. He had lengthy associations with the Chicago Civic Opera (1918–1932) and the Metropolitan Opera (1933–1950), and frequently performed at the Salzburg Festival during the 1930s. He appeared as a guest artist with opera houses internationally, including the Royal Opera House, the Teatro Colón, and the Teatro Carlo Felice among others.

L'incantesimo is a short opera in one act by Italian composer Italo Montemezzi. Its libretto was written by playwright Sem Benelli who had previously collaborated with the composer on his most famous opera, L'amore dei tre re. Benelli finished the text in 1933, and Montemezzi started work on the score, but the composer's unpleasant relationship with Mussolini's government made Italy inconducive to creative work. Montemezzi resumed work on L'incantesimo during the summer of 1943 in Beverly Hills, his home during a 10-year sojourn in the United States. Upon completion of the score, he offered it to the NBC Symphony, professing admiration for their orchestra.
