VIVA LA CALLAS,
Having a heart to heart conversation with GOD. Lo mas grande en la historia.
-From @vxhorusxv
Just imagine that this really happened on a random night in a random year on a random ball of water and rock in an otherwise utterly unremarkable solar system.
-From Robert Palmer:
It's a long ovation. But when I saw her perform Lucia in Chicago she received a 12 minute standing ovation at the half-way point in the mad scene. Set a record that had never been before or since duplicated. As I have said before here on youtube: to see Callas is to believe
-From Robert Palmer:
Having seen Callas 13 times and Price only a few times I can tell you comparing Price to Callas is like comparing a flashlight to the Sun!
-From Melvyn Elphee:
What amazes me is the subtlety and detail even in a live performance relatively early in her career. Nowadays it should be possible to rescue this from the clicks and enable MILLIONS to take advantage of this extraordinary piece of human expression instead of the 355 currently showing!
-From deadwalke:
Can we just focus on her exemplary usage of her chest tones here from the last 4-5 minutes of the duet? Good lord they are some of the most Wagnerian-Baritonish notes I've ever heard from a female singer. And to think they really want to present Pretty Yende as the face of Opera now? God forbid we forget legendary Callas we'd be doing a disservice to all who call themselves an opera lover/buff.
-From Kastrafior:
Mystère d'une voix interstellaire, magie d'une comédienne instinctive, hors norme et passionnément vivante... Mystère de l'opéra, magie d'une représentation sous l'auspice des dieux de l'horreur et du bonheur....
