I'm just trying to help move the thread in a productive direction.
And a better job at that, you could not have done.
So far, you've incited remarkably trivial and inane semantic arguments with about 75% of the people who posted in this thread, you've claimed that any posts that listed bands that you personally didn't consider great weren't "legit"...you've asserted that people who don't agree with your perception of greatness are simply too stupid to understand it...and you've managed to do it all with a very elitist and condescending attitude, and in one thread. Impressive.
I'm going to go ahead and jump back into the subject matter that was originally at hand. Since listing Opeth here, in a thread about the greatest death metal releases, is nothing short of outright blasphemy and thus has rendered my previous post completely illegitimate, I'm gonna go ahead and throw out a couple more albums, however, they may not qualify as "true death metal", or for that matter, great. I'll have to wait for Scourge's authentication before I know for sure.
In Flames - Jester Race and Whoracle
Dark Tranquility - The Gallery
Amon Amarth - Once Sent from the Golden Hall
Eternal Tears of Sorrow - Before The Bleeding Sun
I listed In Flames because those two albums along with a couple of their newer ones (which I don't care much for anymore) are what really got me into metal for real. Dark Tranquility, because I dig their style and they do a good job of interlacing mellow arrangements with the heavy stuff (the intro to Lethe is godly). EToS has a similar sound to In Flames. though unique in their own way, and Amon just kicks ass plain and simple.
