Before he discovered house music and the rave/club scene, Chicago's Bad Boy Bill was a hip-hop-based battle DJ. That experience as a turntablist has given him an edge that most dance-music DJs don't have. Any track he plays becomes his own, as he applies battle-jock techniques -- scratching and cutting -- into the hard house grooves he's become known for. While many house DJs mix by numbers, Bill deftly manipulates the music in such a way that the songs seem to be remixed on the spot -- literally. Catch Bad Boy Bill this Saturday, April 23, at Vinyl, when he brings his Fuck the Experience tour to town with go-go crew the Bad Ass Bitches, Steve Smooth and Jonas Tempel.
