Tom: E
   I just figured out the dominant guitar parts to this song. Most of the other parts were 
more buried in the mix (or in unison).
The tuning is 1 1/2 steps from standard tuning (with dropped D ).
So it's Low to Hi: B, F#, B, E, G#, Db
Intro: 
    p.m. - - - - - - - - |       p.m. - - - - - - |
    p.m - - - - - - - - -|      p.m.- - - - -|            
                                 (  means bend up 1/2 stp.)
1st Verse:
       p.m. - - - - - - - - - - - - - - - - - - - |
(The fill at the end of 1st verse is same as last fill of intro.)
B Section:
    "Feel it... Let it go." etc...
   "I know.... what you.... feel."
Chorus:
       "Step down on the... slivering snake."
       "Rescue yourself..."       
                                  
                     (Bend up full step)
2nd verse:
Same as 1st verse but add the fills that are in intro 1/2 way
through the verse.
B section:
Same as the other 
B section.
Intro: to Bridge:
Bridge Riff:
       "Get up! Get up!"
That's it. These are all the parts of the song. You can figure the complete arrangement. 
it's not that hard.
