Tuning: 5-string down half a step (Bb Eb etc)
Note: unlike most of my tabs, this is not complete. Instead, I've 
presented some of the riffs and a few alternatives. If you really, 
really want to do an exact duplicate of the recording, you're gonna have 
to figure it out yourself, 'cos this song is all over the place!

Verse riff: this is the basics of it, the amount and positioning of 
rests varies throughout the song.
