List of Slipknot band members
Since the band wanted to keep their percussive sound, Greg Welts joined the band to replace Colsefini. Towards the end of 1997, each band member picked a number to identify themselves. In 1998, Welts became the only member to be kicked out of the band and he was replaced by Chris Fehn. Slipknot wanted to have a DJ in the band, but had a hard time finding one because "the people [they] knew who were DJs all sucked!" Sid Wilson approached the band after seeing them live. He proceeded to impress the band with his ability and his antics; Wilson was considered "Slipknot material" and his hiring brought the band's line-up to nine members. The final change in the band's line-up came at the latter stages of the recording process of the band's debut album, Slipknot, in 1999. While the band took a break from recording the album, Brainard decided to leave the band and was replaced by Jim Root.
