Slipknot järjestää oman Knotfest-festivaalinsa syksyn aikana muun muassa Yhdysvalloissa ja Japanissa.
Knotfestin ”virallinen tuoksu” on kamelin lannan (tai paskan) haju. Perkussionisti Shawn ”Clown” Crahan kertoo: ”Slipknot ei ole oikeastaan enää bändi, sillä kyse on kokonaisesta kulttuurista – ja kulttuurilla täytyy olla oma haju”.
Tiedote sanoo: ”Knotfest will have it’s own aroma that will infest your brain, body and clothes for days after the festival is over. Personally picked by Slipknot themselves, the smell of Knotfest will permeate the festival grounds. Oil drums will be filled with camel shit… set aflame to last the entire festival.”
Crahan lisää: ”We did the camel dung on the first Knotfest. It was awesome; it was beautiful. Fans came into the museum and they had to be hit with camel shit. A very distinct smell. You can’t huff it, but it’s got this smell. And it’s not necessarily the most comfortable thing, but it’s not necessarily the worst thing, it’s just remembering thoughts — it’s gonna be a reoccurring thing.”
