+1 to Nergal, especially on Demigod. Slaves Shall Serve, especially the opening, and Before Aeons Came are way too awesome.Conquer All is, too me, the essence of badass, tbh. Fucking ill riff (yes, stolen from anthrax) with those beastly vocals coming in, killer drumming, etc. The only song that I'll play at dangerously high volumes. Unfortunately they kinda butchered it when I saw them live (or maybe the sound people did; it wasn't even recognizable until the chorus).
