Well, I went to the show tonight. The band hadn't played together before (she had to ask the bassist for his last name as she was introducing him on stage), and it really showed. For much of the set, they weren't hanging together at all. There is loose, which can work, and muddy, which can't. This was the later (for most, but not all of the set). I may be off base on this, but IMO it didn't help that they were playing over a tape of backing vocals and synth string sounds. The tape can't push and pull like the drummer and bassist can to adjust.
Also, and it may have just been an off night, but her voice was very thin live - not at all like the scattered fragmentary samples I've heard online. She did make a subtle passing reference to not feeling so good about her throat.
That being said, even with the rough edges I could tell that there were some interesting ideas in the music. They played a couple songs that were very influenced by Bitches Brew.
Oh yeah - she is even better looking in person. No lie. She seems like a bit of a geek, too -- I don't mean that in a bad way, she is just a little awkward in her movements and says things like "golly" and "gee willickers" without a trace of irony. I sort of liked the contrast between her looks, high fashion and dorkiness.
