There's been new interest in the Chicago 'footwork' phenomenon, which is the new school form of Jit/Juke competetive dance. The music is pretty crazy stuff, growing out of booty house and ghetto tech but seemingly endless rhythmic variation. They've set up the new Planet Mu footwork compilation for streaming if you want to check it out...
http://www.npr.org/2010/12/06/131792022/first-listen-bangs-and-works-vol-1-a-chicago-footwork-compilation I've been fascinated by all the competetive street dance cultures since people started breaking in the late 70s. It's something that springs up in different forms independently -- Caipohera in Brazil, Breakdancing in NYC, Jit in Detroit, Juke in Chicago, even the competetive Stepping that's so important to African-American sororities and fraternities. Even more fascinating, I can't think of any analogous dance culture amongst white people.
