I never watch the Grammys anymore - not since rap became de rigueur. Noise, verbiage with a beat, usually objectionable, but not music. I was busy doing things around the house and didn't have time to sit in front of the television, so listened and occasionally looked at the TV. Saw that this was coming and watched Lady Gaga's tribute to David Bowie. I don't know too much about GaGa, nor know many of her songs and have only seen snippets of her performances.
Unbelievable. An understatement. There are artists - and then there is Lady Gaga. I've never seen anything like it. There should be another word for her performance and talent. It was something to behold on the big screen. There is another video of her preparing, scoring, practicing, etc. for this performance that is also very interesting.
