I have recently discovered and become a big fan of avant cellist Zöe Keating. With just her cello, a foot-controlled Macbook Pro that runs Ableton Live, SooperLooper and MidiPipe, a bank of MIDI pedals, live looping, and various plucks and strums and taps and slides - she produces an entire orchestra of sound. She distributes her own music sans record company, she lives in a redwood forest, she has red dreadlocks. There's a lot to like here. She has produced three recordings, Into the Trees, One Cello x 16: Natoma, and One Cello x 16. All are worth a listen. [NOTE: Video shows her playing "Escape Artist" at TED in San Francisco. Turn the sound up a bit so that you can hear the subtle nuances here].
