I think Adele is fabulous. One of my favorite modern voices. But I was shocked at the Grammy performance. It was her worst televised performance ever. I would like to say it was a mic problem, but what I heard was off key for much of the song. The mic does not amplify an off key performance when it is sung on key.
Did you hear Adele at the Grammy's?
It was the most godawful atonal thing. I suspect that she always benefits from pitch correction, but this
time it must have failed, and she and was unmasked. She and the media tried to make up some excuses, but that was no microphone problem; a mic only
amplifies what is coming out of your mouth. No effect on pitch whatsoever.
