Query: If you don't like/love this album, you don't know true metal!!

Machine Head is a true to the heart heavy metal band, no questions asked. This is definitely their best album they've made to date. I heard this not long after it came out. "Imperium" being the first song of theirs I ever heard, I heard it on the "Headbangers Ball" compilation to be completely honest lol. I have been a huge fan ever since. This albums defines who they are musically, even though I do love their direction in "Unto The Locust". Any metal fan that says Machine Head sucks, is not a true heavy metal fan.
