Much too easy as a metal-head as well. My only gripe is that there are a lot of bands in there that aren't death-metal. Every kind of extreme music isn't death-metal people!
Yeah I guess, the only problem was that:
IKEAorDeathVikingDoomDroneSludgeCelticPaganGoreGrindThrashMetal.com was already taken so they had to shorten it a little.
Even easier if you're both swedish and have at least some knowledge in metal bands (coming from a guy that shared rehearsal space with Meshuggah in the late 80's).
A friend of mine grew up in Norrland and sings punk.
Long ago, when I talked to her about the obvious superiority of Death Metal and why Meshuggah is the Answer, she said -- "Oh, drool... some of those cute boys were a few classes below me in school." :-)
While I Bathory was a big influence for a lot of bands, Possessed and Death were both producing rehearsal tapes and demo tapes in '84. Hellhammer (of Switzerland) was arguably more important with their Satanic Rites demo, in '83 [1]. Note I'm not disagreeing with you, just discussing degrees of influence. Bathory's influence would be much more important in the first and second wave of black metal.
I generally cite the triad as thus: Bathory, Hellhammer and Slayer, all of which had releases in the 1983-1984 period. Sodom is also important. Death, less so, since its demo at that point sounded more like speed metal (it was only after the time spent with Repulsion, formerly Genocide, that Chuck hit on the death metal formula). If we're into the 1984-85 period with Possessed, we also need to include Sepultura, Master/Deathstrike, and Morbid Angel.
