First off, I know each album in any band's discography chronicles a different era of their sound, so please don't respond saying, "All of their albums are essential in a different kind of way" etc. What I mean is that I was just browsing for ND on Metal-Archives.com and checking review ratings. I saw that The Knowing seems to be their highest scored one. So my question is this: Is there a general consensus among ND fans as to their best/most essential album? If so, what is it? If not, which one in your opinion is their most definitive body of work? Thanks!
