here is the tab for the remake song shadows fall did on welcome to the machines by pink floyd.

Tuning- the tuning does not matter, i will tab it out in drop C but for you standard players just move down four frets and you will get the same effect. for drop d tuning you move two frets down and for you D-tuners just move down one fret

D---------------------------------------------------------------
A---------------------------------------------------------------
F---------------------------------------------------------------
C--------------------------------------------9-----7-------6/7/6
G---4-4-4-4-4-4-4-4-4-4-4-4-4-4-4-4-4--------7-----5-------4/5/4
C---4-4-4-4-4-4-4-4-4-4-4-4-4-4-4-4-4-----00----00-----00-------

that is how you basically play the song and i think shadows fall did a great job
