Let me also add.....
1. Nirvana, my favorite band of all time, absolutely changed the game, but in doing so the end result years later is they absolutely ruined rock too. Because of them any and everyone thought they could start a band. People who obviously have zero knack for songwriting, zero talent for performing, zero stage energy, and posess zero authenticity all of a sudden started bands. The prices of guitars (specifically old fenders) went through the roof.
2. The advent of mall punk. Yeah, that's right you know who you are HOT TOPIC.... When punk became a mega mainstream fashion it was all over. I have said this since 1997 and I'll say it once again... Punk in its true form is the against the grain, anti-establishment movement. Where do we go when the anti-establishment has become the establishment? That's right, punk died years ago. And fuck all the claims these guys make about punk being alive and well because some kids are out there somewhere playing in a basement. While there may potentially be some kids out there who hold it sacred, that just doesn't cut it. The movement is dead. It's fucking bastardized, raped, and dead. When my bank has posters up to sell savings accounts that were designed and approved by some corporate jag off which have pictures of "punk rock kids" playing in a garage that say something along the lines of "saving for just the right gear to rock the house"........ uuuugh..... It's so fake it makes me cringe. It's been over.
Thankfully, this whole "where do we go when the anti-establishment becomes the establishment" thing applies to rap and will eventually be its downfall too. It may take a while, but it will come. It took rock about 50 years or so to die.
3. I think the concerts most people look forward to and get amped up the most about these days are the ones where someone old is reuniting. Holy shit!!!!!! GN'R!!!!! Holy shit!!!!!!! The Replacements!!!!!!!!! Holy Shit!!!!!!!!! The Misfits with fucking Danzig!!!!!! (How I haven't seen a thread on this board about this one yet is beyond me) Holy Shit!!!!!!! Nirvana!!!!!!! I mean, at this point I think the only bands that haven't reunited are TAD and Husker Du.
This whole phenomena tells you something though.... People really aren't getting excited about new bands so much.
4. The unholy marriage of rap and metal sucked a fat one and turned a lot of people off. Weiland during the 2000 house of blues performance, as the band was about to go into Vasoline, states something about LA. Something along the lines of "this city used to be all about the rock n roll, where's the rock n roll?" And he says something about STP bringing the rock back to LA. And I believe it was at HOB '99 where he says something about being in the era of very bad rock radio music. It was all true. When the best frontman since Freddie Mercury, perhaps ever, is telling you something that he's seeing, it's not an illusion it's really happening. Rock died in front of our faces, on our watch. And all we did was watched as it happened. As we were spoon fed P.O.D. And Default......
5. Another fair assessment that can be made is.....The discontent that Americans feel with this whole 2016 presidential campaign where it's all just so bad and rotten on both sides that it makes you want to just tune out and not even participate.....I liken that same discontent to what most people eventually came to feel about rock music. The choices they were given just were horrid from all angles.
