Have you had a chance to watch this infectious video called Daft Hands - "Harder, Better, Faster, Stronger"? You must wait until the fingers starts coming out. It's pretty amazing. I think towards the end, she started messing up, but it is okay because it's so awesome.
If you were curious, the song is by Daft Punk off their Discovery (2001), and heavily used samples from "Cola Bottle Baby" by Edwin Birdsong.
There's not a whole lot of information on Birdsong on the internet. The only thing I can piece together is that it seems that Birdsong is a funk and soul artist from the late 70s, who's career spans into the mid-80s.
