From a 1960 live performance in the Teatro Colòn Buenos Aires, Argentina, Ponchielli's La Gioconda's libretto was written by composter Arrigo Boito who adapted it from a play by Victor Hugo. A quintessential operatic tale of thwarted love and devotion this performance features the American soprano Lucille Udovich, noted mezzo-soprano Mignon Dunn, longtime Metropolitan Opera member bass Norman Scott, and tenor Flaviano Labo with the Teatro Colòn Orchestra and Choir conducted by Carlo Felice Cillario.
