I'm not a big fan of hers by any means, but I was introduced to her music back in the early to mid 00's before her 'fall'. She had a different type of voice, but I thought she was very talented. Since then, she's just awful.
if I didn't know any better, I'd guess that this vid was taken during her 'fall' from graces... during the days of her decline in health and obvious/rampant drug use. I see on YT itself, it says this was 2011. *shrug* Physically, she looks better than she has in years, but her stage presence is still ... as Soots put it.. a Train Wreck
