This 69-CD deluxe box set contains all the studio recordings that Maria Callas made for both EMI/Columbia and the Italian label Cetra between 1949 and 1969 (26 complete operas and 13 recital albums). Each recording has been painstakingly remastered in 24-bit/96kHz sound at Abbey Road Studios using the original tapes, on Bowers & Wilkins 802 Diamond speakers, and the entire collection has been curated with the greatest of care.
Conceived as a true collector’s edition, CALLAS REMASTERED presents each individual opera or recital CD in its original artwork. It also contains a 136-page hard-back book with essays, a biography and chronology, rarely-seen photos and reproductions of revealing letters written by Maria Callas, Walter Legge and other EMI executives. The opera librettos and aria texts are provided on a CD-ROM.
"The recording now sounds like a million dollars...Restoring to us the sound of the voice as it would have been heard in the studio,” -Gramophone
“A beacon illuminating the mysterious but indispensable art of Maria Callas…You couldn't ask for better than what Warner Classics has done with Maria Callas – The Studio Recordings Remastered.” - The New York Observer
