Good, but not great
I, too, have seen her perform live on more than one occasion. Her voice is phenomenal, she has stage presence and she assembles a tight band of rotating musicians who know how to play. Unfortunately, this disc doesn't quite capture the energy she generates live. If you've never seen her live, by all means download it and give it a listen. it is definitely an entertaining listen and her vocal chops are reason alone. But even more to the point, catch one of her live shows and be ready to be blown away.
