Maria Callas (1923-1977) needs no introduction as she was quite simply one of the greatest singers of the 20th century. Any recording is of major importance and this Traviata from 1958 given in London's Royal Opera House, Covent Garden is no exception. This recording drawn from private tapes has been remastered by Paul Baily using ICA's Ambient Mastering process which has enhanced and widened the sound considerably.
