Ezio Pinza sings Confutatis from "Verdi Requiem"

I will be posting a later version of Ezio Pinza singing this piece for my next upload. This was recorded in 1929 with Rosario Bourdon conducting. The later version I will include is from ten years later with Tullio Serafin conducting. I am sure that the conducting is better on that recording since it is one of the greatest Verdi Requiem recordings. However, it is still interesting to hear how a voice changes over time.
