The Great Maria Callas rehearsing in Paris for her Album with Verdi Arias from his less Known Operas...She is in very good voice for the period!! Much more relaxed and fresh than 1961-1965!! She had re studied with Elvira De Hidalgo!! She tries in 2 different takes the high notes in pianissimo and then in fuller Voice!! Nicola Rescigno is the conductor!! Hope to enjoy!!
