Metal's Retromania (updated 7/17)

The blog Hate Meditations, dedicated to musings on extreme metal, has been doing a series of posts called Metal's Retromania. Looks pretty probing, although I confess to being an inadequate reader, since my grip on the doings and goings of extreme metal (or any metal) has been pretty tenuous for nigh on thirty years (nor really was it untenuous before that to be honest, although there was more active curiosity). But should you be familiar with the zone and up for tangling with an argument, this looks to be a fascinating read.

I invite the metal-informed to assess what is convincing and unconvincing in Hate's argumentations here. 

The subject of retro-ism within metal has cropped up before on this blog, or actually it was Blissblog now I think of it - including the question of what differentiates doom metal from retro doom metal, given that doom metal is already looking back, more or less a Sabbath reenactment society.

From my slenderly-informed perspective, I should imagine retro-revival currents within metal, a folding back on its own extensive history that parallels what has happened to almost every other genre that's a bit long in the tooth - this must get tangled up interestingly with the tendencies within extreme metal to reject modernity: to cast back, oftentimes more than a tad dubiously, to the primordial, the pagan, the Medieval etc etc. 

Tangentially this has reminded me of my favorite TV show of the moment - the Norwegian series Beforeigners, a  wonderfully witty satire of the modern day struggle between multiculturalism versus nativism, the fraught politics of immigration, refugees and asylum seekers, etc etc. It uses a simple science-fiction premise that - if you go with it,  let it be unexplained - yields plentiful amusement. 

Timeholes have sprung up in the sea off the coast of Norway through which people from earlier eras  of the country are popping out, bedraggled, half-drowned and utterly disoriented. Three epochs specifically: Stone Age, Norse (people from both sides of the Vikings versus early Christians conflict - which is why I was reminded of this in the context of extreme metal, church-burning black metal singers etc), and 19th Century. 

As Norwegian society struggles to cope with the influx and help these timigrants, these beforeigners, to assimilate...  well, you can imagine the satiric possibilities. Graffiti slogans like "Norway for Nowadaypeople". Mixed-temporal marriages. And (I'll stop here because I don't want to do too many spoilers) there is also the phenomenon of transtemporalism - people who realise that although they were born in the late 20th or early 21st Century, inside, they are Viking / paleolithic / Ibsen-era.

Rather than metal, though, the Vikings in this series seem to prefer EDM / hardstyle when they are letting off steam and throwing back many horn-fulls of mead
