Some friends and I saw her at Town Hall last night; wow.

To parse that wow a bit: for about the first three songs, I (and the people I was with) were actually a bit worried. Her performance was awesome, and got roars of approval from the audience, but somehow felt a bit too careful, a bit too dignified. But then she loosened up; each successive number was more spectacular than the last, as she fiddled, strummed, danced, and more.
