First thing is you are referring to Poison and Cinderella; that is not and never has been heavy metal regardless what MYV and Metal Edge ever called it. If we do stretch it as far to call it "metal" it is nowhere close to power, traditional, or even what you guys do. When I refer to "metal" and say it was not that big even back then I refer to real metal. Take bands like Attacker; a metal band from the 80s but they would only be able to get back then what they can achieve now in the states, why because no one gave a shit about heavy metal on a large scale.
If your exposure to metal was Poison from your brother I would say "you must first unlearn what you have learned".
I would guess being around DC that you might have been born and grew up around there? If this is the case I cannot believe there were not record store galore around there that would have sold metal and more underground stuff. I'm not talking Record Bars, Camelots, etc which actually all did have metal sections because those chains usually all had the same lay out. But knowing several people and bands from that area who grew up in the 80s and on into their teens in the 90s I know from them there was metal up there. Also consider that bands that came from the area.
Maybe you grew up in Montana, there I could believe there was no metal in record stores.
The fact probably is and I truly mean no disrespect but you are too young for starters, probably had no idea were to really look, and could only go off of what you were exposed to to start you on your way on the metal journey. Unfortunately, and I do understand, not all kids had that bus driver who gave them mix tapes, the camp canceler that gave them Sanctuary demos before the band had an album, or a friend who introduced them to Death, and so on.
cotinued from last night; forgot where this thought was going. HAHA
addition; you mention having Napster going on that you would have had the internet so you would have had much more exposure than anyone in the 80s would have and it would have been much easier to come, that is of course if you took advantage of it. So really you would not have needed record stores for your exposure. And internet has absolutely nothing to do with region. I also can't buy into that thinking about people I know from the midwest who were isolated from anything yet they found a way to be exposed before internet. So the region things does seem like an excuse or maybe just a simplified explanation.
