i think this goes back to the whole false notion that “rock is dead”. which, no. rock isnt dead. but rockism is dying for sure, which is actually making rock so much better right now
most of the reasoning of why “rock is dead” is that rock isnt mainstream and as obscenely profitable anymore, and isnt as affecting mainstream culture as much anymore, which is objectively true (hip hop has very much taken its place as the default american metagenre). but saying that this means that rock has “died” is absurd as saying jazz “died” shortly after “kind of blue” because it stopped being as safe for most white corporate american ears (coughcoughkenburnscough).
rock has only gotten better i think since it “died” imo (which i consider to be about 2008 with the final gasps of the boring garage rock revivalists and post-grunge lunkheads, but its p telling that no one still has come to a consensus on when exactly it “died”). car seat headrest, downtown boys, g.l.o.s.s., issues, vein, black midi, against me, chai. all amazing rock bands founded around or after the Death Of Rock, brashly experimented with accepted forms of the metagenre, introduced more racial and gender and sexual diversity into the scene(s), and still wont be accepted by conservative dadrock establishment because its not led zeppelin.
actually led zeppelin is a good reminder of a big sign of how dead rockism rlly is: the absolute failure of greta van fleet. after years of bitching about “the goddamn trustfund millennial zoomers” ruining rock music cuz it doesnt sound like these white brits aping the art of black american electric blues for white boomer profit, the dadrock establishment (ie non-queer white male conservatives hanging out in country clubs built on indigenous gravesites) did a deal with their supposed devil in basically genetically cloning led zep in the form of four “goddamn trustfund millennial zoomers” (who they were ok with because they werent queer and they were white and male and rich and raised by rich dadrock dads and are ok with all of this) and heavly forcing promotion of them and their aping of white brits aping black american electric blues thru the same hypercapitalist streaming and social media infrastructures they claim to hate. and the best part is, and this absolutely warms my heart to say this, no one fucking fell for this bullshit! everyone seems to know that gvf arent trying to “revive” rock, they desperately want to make sure its “dead”, and thankfully, everyone damn well knows its more alive then ever. maybe not in population but surely in progression and passion
sorry if i come off ranty, i just have a lot of thoughts on this. and to end this by tying up with ur original point @NicoleJS, paul mccartney, the stones, aerosmith, gnr, foo fighters, etc. all will be famous and making a shit ton of $ long after they die. dont feel bad for them at all. focus ur energy on helping the new generation grow and sustain so rock truely never dies
