She's running into issues because she insists on singing the material the same way she always has, presumably with some sort of guidance from her vocal coach. Clearly it sounds like there is even so much he can do at this point.

Her entire approach to live performances needs a reboot.

I'd also love to know what the mix preferences are for all of the in-ear monitors for the band members on stage. Bass 70%, Drums 70%, Keys 65%, Stevie lead 5% LOLOL....I cannot imagine having some of these vocals coming directly into your ear.

This. She could put on a good show if she rearranged some songs, lowered some keys, and played a stage that makes sense for her age. Not to mention digging into her catalog for some songs that translate better with her current capabilities. Trying to croak out the same Stand Back or Gypsy or Rhiannon hasn’t worked for her in at least ten years.

It also freaked me out that she was in the day singing a hit, and it looked like nobody was even paying attention.
