I liked her late 80s/early 90s rock stuff. It was basically Heart-lite, not quite hard rock like Heart but the same melodic material with some pretty good guitar riffs.
I love this song. She looks amazing here. I'll never understand why she wears those ginormous curly wigs. Her natural hair (like this I presume) looks immeasurably better. In fact, it looks beautiful.
No one sang live. The record studios wanted everyone to fake it so nothing sounded different. It's just a live performance but not live singing. If that makes sense.
She can be a great live singer, I've seen many of her concerts, and while no Linda Ronstadt, she does have a powerful voice that can rise above the amplified guitars, drums, and keyboards. But this ain't live.
