John Ardoin wrote in The Callas Legacy about the 1955 Berlin Lucia led by Herbert von Karajan, “If I could own but a single Callas set, it would be this one.”
There was a bis of the sextet, and I offer you this bit today. Along with Callas (listen for the amazing diminuendo), you hear Giuseppe di Stefano, Rolando Panerai, Nicola Zaccaria, Giuseppe Zampieri, Luisa Villa, and Mario Carlin.
(Io son vin-to-ho so-hon co-hom-mosso: Forgive me. I have no love for di Stefano. I know that the sound was glorious, but who cares?)
