another music example is how the destruction of heavy metal coincided with the solo project like Nine Inch Nails or Smashing Pumpkins or other "one man band" stuff taking off. When you take away all the bullshit and leave in the art the medium thrives. rock died and rock bands were replaced by djs and rappers and other small groups. One guy with a touring band or just a computer. EDM dominates now and even if you tried to replicate the biggest edm song from the last year using real instruments it would be insanely expensive and not fucking worth it.
The music industry in general was destroyed due to the advent of the digital age. Napster, file sharing, mp3s, and then later streaming all led to the death of the music industry, which relied primarily on albums and tour revenue.
When albums started to flop as a format due to physical media becoming outmoded, it shifted towards tour revenue and 360 deals, which is where we saw this glut of celebrity endorsements from musicians/artists and you saw a lot of folks trying to work around that and make money (Trent Reznor/NIN was pretty notable for this with giving away music or the 'pay what you feel'/tiered payments for some of his stuff, going all in with ARG marketing, taking stabs at Chris Cornell, reworking his touring contracts and then eventually getting into scoring music, but there were others, like Radiohead, for example.)
Part of the issue is that rock music died because it wasn't a sustainable model and because rock was clinging to the album format. Top 40/Rap/EDM are all singles driven and you don't really need/care for whole albums. Plus tastes were just generally changing to coincide with what folks were doing/caring about now. You ignored how country became a huge fucking deal for a bit, too, and that was because it basically superseded rock -- you had songs about girls, beer and partying, which is what rock music
used to be about. Now that glitz and glamour is with influencers and retards like Hassan.
And yeah, part of it, too, is cost efficiencies, like you mentioned. It is far cheaper for some dipshit with a laptop and Serato to go on tour.
But the biggest change and the shit that's driving
all of this is the death of monomedia. We don't have MTV marketing what is 'cool' to folks, working with record label marketing teams to push this artist or that band. I don't know how old a lot of the people are on here, but living in certain parts of the States or Canada back in the 90s was like being 8-9 months behind things, or sometimes not even getting things, even with shit like MTV or Rolling Stone telling people what is cool. For stuff that was more niche, (eg, computer games, Warhammer, anime, certain genres of music, whatever) you were sometimes well and truly fucked for options.
You have shit like YouTube, SoundCloud, BandCamp and even Spotify where artists can release music. And if you're a guy who only listens to Norwegian death metal? You can burrow in like a tick with that kind of music and never listen to anything else because you aren't starved for choice anymore.
Same shit with movies, books, whatever. There's indie guys doing shit in the vein you'll probably like. There are authors going the self publishing route. Bands that are hustling doing their thing. There's no Michael Jackson/Beatles/Elvis Presley/whatever-tier types anymore, but is that
really so terrible?
Unfortunately with that comes a lot of shit. And you have big companies/studios/etc being even more risk averse (a trend you could see with how and what record labels were doing in the early 2000s), not wanting to take risks and just retreading the old faithfuls. The Spielbergs. The Pacinos. The Scorceses. The MCUs. The reboots. Etc.
