You have Misfits as Punk and Fugazi as not Punk? I love both but you can put them into a lot of things. For me, DIY is punk as fuck, and they both go there. Also early NYC music that may get construed as New Wave or No Wave. Fine with it any which way. Their influence is far and wide and they all did it their way, with or without a crowd. Misfits played MSG a few years ago--and it's difficult to think of anything more not punk. It's all convoluted. Hell, I'd argue Morphine was punk but I don't think they'd care, nothing loud or jangly. I think PUP is fun, but I have a monetary threshold and venue about seeing them. There's a lot of great bands out there--just saw the oranges band in Baltimore and it was freaking great. They're old now, never made it and their ethos is punk as fuck, although their crowd is not. But that crowd looks like missing teeth dock workers with a beer in each hand and a fun time is had by all. And I'm down with it like the Motards back in the day. Velvet Underground is still my fav band and if they dropped down today, they'd still be ahead of their time. The rest is what it is. Replacements, don't care, still one of a kind and Bastards of Young will always be punk. Now I'm going to sit back and listen to Ritchie Daggers Crime for the millionth time and wonder why anybody would ever anoint themselves gatekeepers of this.
If I was gatekeeping, I'd probably argue Punk died in late 70s early 80s. Kind of like Abstract Expressionist--you can do it now because everybody understands the language, but it's not the original stuff. Wouldn't even 4th or 5th generation.
