Maria Callas, who sings the title role of La principessa Turandot, had previously sung the role 24 times in 18 months in 1948-49 before dropping it from her repertoire.
The album was newly remastered from the original tapes at Abbey Road Studios in 2014.
Tullio Serafin, the conductor and Maria Callas's mentor, takes an almost Wagnerian, symphonic approach to the score of Turandot, prioritizing line and narrative over 'oriental' coloring.
Giuseppe Nessi, who performs as L'imperatore Altoum on this recording, created the role of Pang in the 1926 premiere of Turandot.
The last duet and finale of Puccini's opera Turandot were completed by Franco Alfano after Puccini's death.
This recording of Turandot was made in cooperation with E.A. Teatro alla Scala, Milan, in July 1957.
