Shadows Fall - Welcome To The Machine- Pink Floyd Cover Tabs

Ok just to start off this is my first tab. It's the best cover I've ever heard and when I play it i play it this way
also, theres a different kind of palm mute lots of people use where you set any finger on your left hand (for righties)
gently over the first fret on E  A and D. that will be noted as X, whereas other mutes will be a period

key
alt. mute=X
palm mute= .
slides= /
hammer-ons= h
