I have very fond feelings for Baker's Dozen, and think it's one of her works most easily adapted to a ballet-trained cast. It's very beautiful, but also very elusive -- lots of appearing and disappearing going on. I'm glad that the work is being staged various places since Tharp isn't really maintaining an active repertory currently.
One thing that she has here in common with Balanchine is a bone-deep interest in music and its relationship to movement. As with much Balanchine, if you don't like the music, you probably won't like the dance, but I've always thought both of them were extremely charming.
