Tabbed from a video I found of Electric Wizard performing the song. I play it in
C# standard, but it sounds like it might be correctly played in C or B standard.

Riff 4a - one of the guitars plays the same riff with a different rythm after one rep of 
riff above

And a fact about the song; the title comes from the Christopher Lee hammer horror film 
rites of dracula."

Enjoy.
