Ah, 1997. Slipknot vocalist Anders Colsefni had just stepped down to backing vocals and percussion to make way for some new vocalist named Corey Taylor. Chris Fehn and Sid Wilson weren't even in the band yet and Slipknot were only one year out from releasing their now-rare and pretty weird demo Mate Feed Kill Repeat.
You can watch Taylor's first-ever performance with Slipknot above, which took place on August 24, 1997 at the Safari Club in Des Moines, Iowa. One thing is for absolute sure, and it's that this is not the Slipknot that would be present in the public eye two years later.
