Only listen to a couple of these, but Behemoth > Zyklon for sure.
ONly band I really like is Belphegor, but my favorite is Bloodthorn. Grab their 07 release Genocide. It's so heavy and just fuckign good.
Melechesh is my favourite blackened death band. Yeah there's so many missing in this poll. No Dissection?!?!
Pluralitas non ponenda est sine necessitas (Occam's Razor).
And 1349, while it has trace influences of death metal, doesn't have them to the degree that they can be classified as blackened death metal.
OK, on "Before the Aeons Came" Nergal uses just his BM vocals, certainly a vestige of their earlier days, and you can hear that in the instrumentation as well. But the rest of the album, musically, is straight death metal.
Angelcorpse is good and all but everyone knows that Order From Chaos blows them away anyday of the week. Underrated band deluxe.
Infernal War
