As well as lending his percussion talents to the band, Fehn has also sung backing vocals on a number of songs Slipknot has both recorded and performed live. Outside Slipknot, Fehn is a very keen golfer, and evidences this on the band's 2006 DVD, Voliminal: Inside the Nine, where he is interviewed while playing golf. Fehn describes himself as a "big fan of the band" and says of Slipknot, "the world needed something like this. " Slipknot bassist Paul Gray stated in an interview that Fehn "often brings humor to the band. " and that they "definitely need that guy. " Prior to joining Slipknot in 1998, Fehn was close friends with Slipknot's percussionist Shawn Crahan. According to Fehn, he had originally asked Crahan if he could be drummer Joey Jordison's drum tech. Shortly after his request was made, Fehn was given an offer to play percussion in the band. Fehn was then given a rough demo that contained all of Slipknot's songs. Fehn has said that "Spit It Out" was the song that stood out to him the most. Fehn then tried out on percussion and was subsequently made part of Slipknot. Of the nine members, Fehn was the eighth to join the band.
