By 1971, Don Carlo had firmly secured its place in the operatic repertoire, becoming a benchmark for any Verdi singer aiming to prove their mettle. The artists on this recording rise to the occasion, delivering performances of remarkable conviction.

At the heart of the recording is Montserrat Caballé, whose voice is at its absolute peak. As Elisabetta, she is simply radiant, her legendary ability to float pianissimi given full reign in this role. Yet, this is far more than a mere vocal showcase—her portrayal is imbued with deep sadness and despair, her impeccable technique serving to create a deeply sympathetic heroine. That said, she holds the climactic high B at the opera's close seemingly forever. Good taste? That is subjective. Thrilling? Objectively true.

Another standout is Shirley Verrett as Eboli, who hurls herself into the role with an almost reckless intensity, making for a commanding and passionate performance. Bruno Prevedi emphasizes the lyrical side of Don Carlo rather than the dramatic, but his Italianate style is first-rate. Meanwhile, Vicente Sardinero and Bonaldo Giaiotti offer excellent performances as Roderigo and Filippo, respectively.

, though there is a small break in the duet between Carlo and Eboli.
