If you didn't know, this is the old version of (SiC), which is off their "first" album, Slipknot. Mate,Feed,Kill,Repeat is actually their first CD, released in 1995 or 1996. The song is better and worse then (SiC) and has a bad ass solo-(which I tried to tab)-so just enjoy the tab!
This is in Drop D Tuning (And yes I do know they play in Drop C, I just like Drop D better.)
