I kind of don't get your point, and I mean, you write A LOT LOL...
I know I write a lot myself but damn....that's a lot to read...but I guess I'm being whiny cause I'm at a moment when I'm maybe too tired to read it all, but here's what I'd say quickly, as a HUGE metal head who also appreciates early grunge like soundgarden, Alice in Chains and Nirvana but who honestly HATES hair metal (I mean stuff like Winger and Ratt....UGGHH!!! I can't stomach it at all....) and who is probably a bit younger than you (I was born in 1980...). Also, I like breaking points down into numbers and letters to make them easier to follow lol.
1) I don't really see the point in harping about how one band or one music movement like grunge "killed" another like hair metal.
For one thing: A) I have never been one to usually like music that is popular period. While I did like grunge, other than Soundgarden who were my favorite of those bands, I was never CRAZY about the others, I just liked AIC and Nirvana I didn't like as much as them either, but still did dig them.
But FOR ME...if you want to take metal, or most music I like...I find it's almost always the underground stuff I like best. Sure, Metallica in the 80s and some other bands who were big in the 80s in their PRIMES were great, but even if you ask me about that era I'm thinking about the extreme bands metal bands like Death, Venom, Bathory, Celtic Frost and Hellhammer, Carcass, Mercyful Fate, King Diamond, and then...
B) as you move into the 90s and start talking about "the death of metal"....I mean FAR FROM IT!! Perhaps the death of HAIR metal but I don't really consider a lot of that music TRUE METAL any ways....more rock music. No offense....but WHY PAY ATTENTION TO WHAT THE PUBLIC EVER VIEWS AS POPULAR OR REALLY CARE??!!
When I became a metal head and general music fan in the 90s....while hair metal was dying and grunge was taking over and all that.....the bands I REALLY discovered were going strong like Suicidal Tendencies, Faith No More, Rollins Band, Rage Against the Machine, and then there was the explosion of Norwegian Black Metal in the early 90s and I came to love Mayhem, Emperor, Burzum, Dark Throne.
Over in Sweden the Gothenburg scene first open in the mid to late 90s with In Flames, At the Gates, Dark Tranquility and Finland was producing bands like one of my all time favorites, Amorphis, and extreme death metal was growing into it's own thing down in Florida with bands like Immolation, Suffocation, Deicide.......I was discovering other bands as well in the 90s like Entombed, Fudge Tunnel, Biohazard.
Your focusing on what was or wasn't POPULAR ON THE RADIO IN THE 90s seems to have left you not recognizing what was going on in the underground AND IN MY OPINION IT'S ALWAYS THE UNDERGROUND WHERE THE BEST STUFF HAPPENS.
But anyways.....I mean, you seem to like to complain about Grunge music "killing hair metal".....but musical trends just happen naturally and there's no controlling what will become popular or what will fall out of fashion.
That's why I just have never cared what was or wasn't popular at any point in time.
I don't listen to the radio and never have much, and while back as a teenager in the 90s I did discover some good stuff from MTV (mainly watching Beavis and Butthead hahaha....) my learning about music from TV and radio pretty much ended after the late 90s.
Since then it's mainly the internet and friends who have helped me discover the music I like.
So yeah...I mean, I like grunge a LOT more than I ever liked hair metal (which I don't like), but I like extreme metal and underground metal a lot more than I ever liked grunge on most of that was NEVER popular.
Why lament changes in popular musical taste that probably couldn't have been controlled anyways?
Who knows why certain music becomes popular and other music doesn't, and why blame bands like Nirvana and Pearl Jam and Grunge bands for trying to do their thing as if they committed a crime by pushing hair metal into the background?
They were just trying to play their style of music.
I personally just don't care what is or isn't popular and find the underground to be where it's at...but I'll tell you that grunge had little to no effect on underground metal and it's fans. We thrived then and we thrive now.
