Giovanni Martinelli - Celeste Aida - 1929 Vitaphone [CORRECT PITCH]

This footage is known among aficionados, but unfortunately the copies heretofore seen on YouTube have audio that is incorrectly pitched (about a half step too high). I have restored the correct pitch so that the performance can be understood with the proper relationship among the pitch, the body, the vowel balance, the cover, the intensity, vibrato, etc. Enjoy!
