Here's a thought that has probably never popped into your head: I wonder what it would sound like to have Slipknot singing the Spice Girls. But Bill McClintock did, bringing fans what he dubs The Slip Girls doing "If You Wanna Breathe My Sulfur". Posting to YouTube his mashup featuring the music from "If You Wanna Be My Lover" with the vocals of "Sulfur," plus a solo from The Black Crowes thrown in for good measure, McClintock captions the piece, "Sorry for this." If you like his work, McClintock is also responsible for putting Slipknot with The B-52's and Black Sabbath with The Temptations. Which have been some really cool mashups you've come across?
