The most difficult thing in this song is the master of 
natural harmonics.
For example, for the first harmonic mesure 9, 15th fret, 
B string, sounding a high A, IA smacks the string 
above the 15th fret. By doing that, he avoid the noise 
of a pick. To do that, you'll need great pickups, and 
wouls better praticing...
Be careful to the very-fast shuffle measure 41 to 64.

Guitar Pro con't play the hamonics IA plays, so I've 
include a track for the sound. Right fingering is in the 
"Lead gtr" track.
