During the Vol. 3 era Slipknot introduced their "Death masks", these masks were latex castings of their own faces. Originally they were used in promotional photos taken at the Houdini mansion, where they recorded Vol. 3, the masks were also used in the music video for the single "Vermilion". During which, when the band members wear the masks the protagonist sees them whenever everything else around her is moving too fast. Also, during live performances of the song the band members change in to their death masks. However they have only ever played "Vermilion" live in 2004-2005 and it remains to be seen if they will wear their death masks when they perform in after the AHIG era.
