Make sure you get the new remastered versions. I have the old Captain Trip version of "Tanz der Lemminge" and the sound is more than a bit muddy; maybe I'll actually like the album when I hear the remastered version.
Lord Lucan, isn't at least one of the bonus tracks on "Phallus Dei" actually an instrumental version of one of their singles (I forget the name at the moment), and not from "Tanz der Lemminge" itself?
