What comes to mind immediately for me is Spaceghostpurrp. He used to be friends with A$AP Rocky and his collective but he fell off and now all he does is go on schizophenic rants on twitter and Instagram live
Kate Bush I've decided isn't an lolcow after all. She's certainly unique but she also is just living her life making music. She never went away and I wouldn't call her reclusive. She did the tour and she raised her son and rereleased her entire catalog of music.The Clash
Billie Joe Armstrong
Wait a minute...
Actually, let's just save ourselves some time and say "Every punk or goth musician not named The Ramones, Siouxsie Sioux, or Voltaire"
Other musicians I'd consider to be massive lolcows...
Insane Clown Posse
Cledus T. Judd
Then you've got the third category of people who either blur the lines between "massive lolcow" and "brilliant troll" or blur the line between "total sperg and borderline lolcow" and "musical genius"
For the former group, I've already mentioned GG Allin, Seth Putnam, and Andrew Eldritch (though Eldritch seems a lot more self-aware once he got off the speed and the meth) and Negative XP.
(There's a reason why he did that Ramona Flowers song in a punk style, and it was because he knew it'd piss off the Woke Left...)
The latter group of "spergy lolcows that were also musical geniuses" would include guys like Carter Stanley, Jim Morrison, Tim Wilson, John Lennon, and Wolfgang Amadeus Mozart
Musicians who turned out to be horrorcows would include Charles Manson, Bing Crosby, Absurd, some of the Memphis horror rappers from the 90's, Bard Faust, R. Kelly, and Ike Turner.
He also spent many decades doing every drug known to man, getting into lots of slapfights with other rock and metal musicians, chasing every trend known to man, screaming at some black metal bands because he became a born again Christian, and nowadays is best known as an Alex Jones fanboy. And at the end of the day, he still failed at being bigger than Metallica.I'd also list Dave Mustaine who, upon getting fired from Metallica, said he'd start a better trash metal band, but he did actually succeed. In the same vein, every "metal/punk grandpas" band.
To be fair, the first part also applies to Alice Cooper and a fair number of other musicians as well. By his own admission, AC just can't remember the second half of the '70s and the first half of the '80s.He also spent many decades doing every drug known to man, getting into lots of slapfights with other rock and metal musicians, chasing every trend known to man, screaming at some black metal bands because he became a born again Christian, and nowadays is best known as an Alex Jones fanboy.
