Album: 2008's Godspeed on the Devil's Thunder
Goth factor: H. P. Lovecraft drunk on absinthe in a cemetery holding a copy of the Necronomicon in one hand and the Egyptian Book of the Dead in the other while telling Edgar Allan Poe about his recent trip to Hot Topic.
Is the song egregiously, amazingly long? Nope! A perfectly manageable bite of putrid pestilence.
