The first video is from Luciano Pavarotti’s operatic debut as Rodolfo. One can hear that the audience understood that they were witnessing something great as they listened. Listen to what happens after he sings the high C near the end:
Next is Luciano 18 years later when he was around 44 years old:
Notice how his voice has changed. There is some essence that is his “Pavarotti” sound, but in the later video, he has obviously gained some ring, strength, and confidence. The older Pavarotti is also playing it safer in some spots (notice how the younger Pavarotti sings a pure “eh” on the Ab before the high C and the older Pavarotti sings an “uh” on the same note.)
I like both equally though. What do you think?
