Montségur – Iron Maiden 
Track 4 on Dance of Death 

This is probably the heaviest song on Dance of Death and its awesome. I think that all of this is pretty accurate. Apologies for no solo but i'm nowhere near good enough to figure it out.

There you have it, enjoy. I'm sure you'll figure out the song structure yourself. Feel free to make corrections or add the solo.
