No idea what this thread is about but when I last saw Mastodon with my dad it was just after the latest album came out so ... eh. First time I saw them the set was 90% Remission. I'm sure some of the heaviest riffs ever recorded are on that album.
Sepultura - Roots
Sepultura - Against
Slayer - Divine Intervention
Malevolent Creation - Stillborn
Biohazard - Kill or Be Killed
(I don't think Biohazard are disliked in metal, but metallers just do not pay attention to them.)
Dying Fetus - Stop At Nothing
Obituary - The End Complete
(Metallers don't hate this album but it's just passed off in comparison to their first 2 albums.)
Pantera - Reinventing the Steel
Carcass - Heartwork
