Riff C (verse 1&2 only) This is where Mr. Knut M. Valle starts to get weird
by doing things differently each pass of the riff.  Just listen for the
nuances and the slight trills he uses to create tension.

From here I believe he goes up a fifth, but it sounds like he improvises
this next part, so your guess is as good as mine...

That is the majority of the guitar that I can discern from this song.  If
anyone can discern more through the wall of keyboards, or even tab out that
insane-ass solo, please feel free to e-mail me or the Reaper.  Otherwise,
if you own the album you are probably very familiar with the structure-enjoy!
