The weird thing about Six Feet Under is that even though they're probably the most commercial death metal act around, their production sounds like total shit. It's like Chris Barnes can't even sell out right.
I really wish Johann had done at least one more LP with them. He was such a great vocalist. That being said, Messiah is one of the best vocalists in the metal genre.
I still kind of regret being to lazy to go to the Candlemass 20 years anniversary show, seeing Längqvist singing A Sorcerer's Pledge was probably pretty awsome.
