Question is how much of an engineered movement Grunge was? Was is engineered from the start or taken over once Seattle kooks took notice and figured it could be used. Grunge was much better vehicle for nihilism than synths, that's for sure.
Now that you mention it, I remember a push from corporate music to go back to the 1960's in the late 1980's, maybe culminating in the 20th anniversary of Woodstock in 1989. Roughly when synth-heavy music was pushed out of style. I remember MTV showing clips of a bunch of hippies in mud up to their ankles as though everyone was supposed to just be in awe of how wonderful it was. Supposedly that farm field still stinks on warm days. I can not imagine who in 1989 under the ago of 30 thought there was anything attractive in it. But it was pushed and pushed hard.
Then later, in the Clinton years, the push seemed to be to put a stop to the 1980's by going back to the 1960's. Bell bottom pants made a come back, as an example, when they were an object of ridicule just a few years earlier. In the 1980's people wore clothes that looked new, while in the 1990's people bought new clothing that looked worn out. Pay full price for something already worn out--sums up the '90's. In the 1980's clothing made people look good, while being reasonably modest--in the 1990's clothing made the vast majority of people look ugly and moved towards immodest. Bob Moog only invented the synthesizer half way through the 1960's and it took years for them to catch on, and longer still for such technology to become affordable. So basically any instrument the Beatles did not use was out of style. Is that what grunge was? The Beatles turning it up to 11 and going full nihilist?
Not sure how engineered the grunge scene was, but there seems to be a definite push. The 1980s were a time of high economic growth and optimism about the future. Technology was surging, but it was still on our side so to speak, PCs were just a very useful tool that helped you type and store documents, crunch numbers but did not intrude much into your social and private lives, and the globalist grid which was already being set up hadn't hit hard yet.
The 1990s was the decade that saw some acceleration in globalism, with NAFTA being implemented. This is when you had an acceleration of immigration in the US fueled by Mexican farmers going out of business due to NAFTA. Even places like Fresno or LA were still majority Heritage Americans in the 1980s, and Orange County was a staunch white conservative stronghold. The Midwest was starting to be gutted with the acceleration of outsourcing.
At the same time, you had the first generation of Boomer offspring coming of age. The parents of kids from the 80s had not grown up in the hippie and disco era, they were already in their 20s when those mass cultures hit. Not the case for the youth in the 90s, so you had the first generation which has grown with more familial turbulence, and the Cobain archetype of the disturbed white suburban kid, although still not prevalent, was present.
In the early 90s as well Afghanistan was in civil war chaos and the opium flowed freely from there into the US, until the Taliban came to power in 1996 and stopped it. Every mass music movement had a drug that went with it, and to some degree the music encouraged its use. The 1960s pushed pot and LSD, disco had cocaine, rap had crack and for grunge it was heroin, drug of despair.
Kurt Cobain's wife Courtney is from a deep state family, her father managed
the Grateful Dead, which was a deep state operation that distributed tens of millions of LSD doses to their following. He was a talented but disturbed young man who was manipulated by his wife, her father claims she killed him.
Besides grunge, the music that emerged in the 90s was fairly satanic in nature, with acts like the Red Hot Chili Peppers, Nine Inch Nails and genres like death metal. "Alternative", which was the label they went under, was mostly dark in nature and the contrary of the more uplifting music from the 80s. It was also not really alternative, being a highly corporate genre pushed by the music industry. This is when also the crack epidemic appeared alongside gangster rap, another genre heavily promoted by the music industry, whose kingpins like Lyor Cohen pictured below were also invested in the private prison complex, one of the most openly cynical manifestation of popular music weaponization.
