As we're sure you're aware, last weekend was the second-ever Knotfest. If that title means nothing to you, it's Slipknot's own motherchuffing festival! A weekend of maggots and moshing as far as your drunken eyes can possibly conceive. But on the Friday night, campers and special guests were treated to a special kickoff party starring Butcher Babies, The Black Dahlia Murder and headliners Suicide Silence.
