This song is simple as anything, the main chords the bass is playing on is D-G while the 
is just holding down a D chord


the main guitar line is

Figure A            (0:07 begins on this point)
e-------------------|------------------------------------------------------|
b-------------------|------------------------------------------------------|
G-14-14-14-14-14-14-|14-14-14-14-14-14-16-16-16-16-16-16-12-12-12-12-12-12-|
A---0--0--0--0--0--0|--0--0--0--0--0--0--0--0--0--0--0--0--0--0--0--0--0--0|
E-------------------|------------------------------------------------------|

then at 1:53 it changes to struming so simply

Figure B
e------------------------------------------------------------------------|

at about the 3:05 mark a second guitar in the background plays
Figure C
e------------------------------------------------------------------------|
b------------------------------------------------------------------------|

then at 3:42 the first guitar goes back to playing figure A until everything winds down

And thats essentially it. Most of the song is on the Bassline, the synth/organ, some 
and lots of feedback.
