Artist: Slipknot
Song: Purity
Album: Self Titled (the original release)
Track #: 9
Bassist: ?#2? Paul Gray

Transcribed by: Marc Brokate

Tuning: no matter what you use cuz Slipknot definitely play 2 tunings.
On the s/t they used Drop B, but on most of the tracks on Iowa they used Drop A.
So you use either Drop B (B-F#-B-E) or Drop A (A-E-A-D) for this song.

Start right after ?Frail Limb Nursery?
