For those who don't know, Slipknot is not just a crazy heavy metal band. Their lead singer is also the lead singer of Stone Sour (Looking at you through the glass). As a result, this album contains some true heavy metal songs, some more mainstream metal songs, and a couple of great soft songs (such as snuff). This is pure gold for Slipknot fans, and might just be the album that sends Slipknot mainstream.
