OP its no use just asking for a band name with a genre described to us.
we need to know more
like
what are you singing about?
what kind of blackened death are you, - passionate and crazy or technical and sumber?
you see i would come with different things with this knowledge.
if you were like Behemoth and sung about the rise of Babylon empire circa 800bc then i would go for
Babylonia Extermina
or Exterminate Babylon
Rising Sun (as this was the empires name)
you see different names for different music/lyrics.
not as simple as just sitting around and thinking up random words.
it has to mean something.
