Carlo Bergonzi is heard at his absolute peak, delivering the kind of effortless, expressive vocalism that defined his career. Caterina Mancini, stepping in as a last-minute replacement for Leontyne Price, may not match Price's legendary stature, but she holds her own with a rich tone and solid technique. Anselmo Colzani adds a welcome layer of warmth and humanity to Di Luna, his beautiful tone offering a more sympathetic take on the role. The music featuring the leads is largely intact, though some introductory and chorus material is missing.
