Zoe Keating formerly of Rasputina, doing solo cello work with extensive live looping and sampling. Kind of like a one-woman ambient Kronos Quartet.
Bonus: radiolab appearance streamable or downloadable here.
Having fidgeted with a looper pedal for a short time (before realizing I needed to commit a lot more energy to learning how to use it than I had available) I'm quite blown away by the things she accomplishes. Apparently she's using a chunk of software called Ableton Live, which I totally need to dig up a copy of.
Do yourself a favor and listen to the radiolab bit. It's quite awesome in the true sense of the word.
