Maria Callas – Unforgettable arias sung by the most iconic diva of all time – remastered for the first time in high-definition sound from the original tapes, for an unprecedented sound quality that shines new light on the voice of Maria Callas. Allan Ramsay, remastering engineer at Abbey Road Studios: “With high definition, you’ll be able to experience sounds which have only been heard so far by people who were either present at Callas’s recording sessions, or who had access to the unique master tape … All we wanted to do is remove the specks of dust, as it were, and wipe the glass clean.”
