If you have a spare 4.5 minutes, watch this video.
Her name is Imogen Heap, and apparently she's been around for some time. She's even been nominated for 2 Grammys. I think she'd be great on SNL. They've had some amazing bands this season. I usually NEVER watch the bands, but Wilco, Vampire Weekend and even Carrie underwood have been highlights.
Oh, could you tell I finally learned how to embed video into my blog?
