i can't argue with you, you're right, i just wish the term "hardcore" didn't get so badly co-opted. it is a type of metal, nowadays, and has been since about 1990 - which is a long time, longer than a lot of it's listening base has been alive. but hardcore was initially a type of punk rock that really despised the metal mentality, and there's still a bit it of it out there.
the t-shirts and jeans uniform was initially a rejection of fashion as bourgeois bullshit, but it got predictably warped around. anti-fashion as fashion. it's not me, but i'm not blind. i mean, i'm old enough that, for me, dressing simply is still about toning it down to get the logos off my chest and the trends out of my head, but i know i'm atypical...
anyway, these are good videos. i'm glad you're doing that. it's time for another generational shift in a big way, this has all been a parody of itself since it started, and reducing the previous one to a joke is a part of that process.
