You have to be a terrific snob not to see the appeal of Slipknot

Every development in heavy music is derided by mainstream critics. When Black Sabbath and Led Zeppelin emerged in the late 1960s, they were sneered at for their lumpen, troglodyte stupidity. A decade on, AC/DC were reviled for precisely the same reasons. When Metallica and Slayer helped lead the thrash metal movement in the mid-1980s, it was at first only enthusiasts for extreme noise who cheered them on.
