In 1996, when the band finished recording their demo album "Mate. Feed. Kill. Repeat.", Slipknot saw its first line-up change when guitarist Donnie Steele left the band and was replaced by Craig Jones. Shortly after, drummer Jordison said they needed a full-time sampler and Jones took the position as "he liked doing that anyway." Mick Thomson then joined the band to be the new guitarist. After "Mate. Feed. Kill. Repeat." was released, the band were working on new songs which needed more singing melody and the then-lead singer Colsefini had a hard time with this. In 1997, Corey Taylor was asked to join the band and after practicing with Slipknot "everything just clicked." Because of that, Colsefini was moved to backing vocals and percussion. However Colsefini was unhappy with his new role and left the band a month later.
