I picked 6:00, New Millennium and ItPoE-1, because with all THREE of those songs you know EXACTLY what you're getting, right from the first NOTE! These songs all come out of the box hard and heavy, instead of starting out slow, or trying to sound "pretty." Not that there's anything WRONG with the ballads or pretty melodies, but I like a song that isn't SUPPOSED to be subtle not trying to SOUND subtle. I think all three of those albums, along with Train of Thought, might be good for turning a "hardcore metal-head" onto DT, if it's someone who has no familiarity with their music.
