Pavarotti has a light voice for Calaf, and you sometimes wish for a deeper voice, but his high notes are magical and he creates a strong characterisation nevertheless. The tenor who sings Calaf to Nilssons Turandot on the Molinari-Pradelli set is Franco Corelli. He is a different Calaf from Pavarotti. More baritonal, with equally powerful high notes, he is more powerful and proves to have a nearly superhuman voice. Sometimes he lacks warmth, however, and is less intigrated than Pavarotti, sounding somewhat aloof, grand. The supporting cast on the Mehta set proves stronger than the EMI set. Renata Scotto sings well as Liu, but Caballe is more radiant and beautiful with Mehta. The sound in this set is truly brilliant. The scale of the stereo is magical, increadibly clear. The playing of the LPO, and the voices of the singers are both caught well in the recording.Mehta proves very strong, the score has never sounded so good.
