This country came down to two choices, both of which would have been worthy. The tiebreaker went to Behemoth over Vader simply because I have been able to hear much more of their catalog. Vader's stuff is sometimes hard to come by. Behemoth has always put out great albums, whether in their black metal early days, their blackened death crossover, or their more recent occult death metal material. Nergal has been recovering from leukemia in recent months and just recently made it back to the stage for the first time.
