This is such an awesome song.  This was the first Fear Factory song I
heard and I have since tuned in to some of their other stuff and it
sounds pretty cool.  I know Fear Factory uses 7-string guitars, but
I do not own one or know anyone who does, so I tabbed it out in Drop C.
Play the whole song with distortion.
