 The album 's recording process was " very aggressive and chaotic " , as producer Robinson strove to capture the intensity that the band created when performing live . Within three days all the drums were recorded , which contributed to the raw , live sound on the album that the band considers integral to its musical direction . By November 11 , 1998 , the recording of the album seemed complete and the band returned to Des Moines . During the Christmas period , guitarist Josh Brainard , who recorded on all the tracks to that point , decided to leave the band . The reasons for his departure are unclear ; it was widely thought to have been because of family constraints , however , Brainard dispels these rumours , explaining that " some decisions were made that I wasn 't particularly happy with . " His replacement was Jim Root , with whom the band returned to the studio in February 1999 . Slipknot finished recording during this period , with two extra songs : a re @-@ recording of " Me Inside " , and a new track called " Purity " . The mixing stages were very challenging , as drummer Joey Jordison and producer Robinson mastered the entire album with analog equipment , instead of the then more common method of using digital formats . " Wait and Bleed " and " Spit It Out " , which had appeared on the demo prior to the album , were released on the album , also ; the demo songs " Interloper " and " Despise " are available on the digipak version of the same album . " Snap " was featured on the soundtrack for the film Freddy vs. Jason and " Eyeless " appeared on an episode of The Sopranos .
