You can hear about plenty of artists uniting or representing a movement in the USA esp 60s.
The story of Rodriguez is one of my favorites. He literally had no idea he had been the root of music for social change in Apartheid South Africa.

"The first white anti-Apartheid movement derived [inspiration] from a few rock bands," Bendjelloul explains. "Rodriguez was the first artist that actually had political content that was anti-establishment that got heard. ... By remote control, Rodriguez was actually changing a society."
They sold music to the huge boomer population when they were young, by the 1980s those same Boomers voted for Reagan in considerable numbers and were buying Debbie Gibson and Rod Stewart albums. RATM sold music to pissed off GenXers when they were young, by 2020 they were voting for Biden. It’s not revolution, it’s youthful angst that gives way to responsibility and lower testosterone levels.
The point is that those pissed off teenage GenXers would be horrified to vote for any Dem candidate for the last 20 years. All of them were/are part of “the machine” but time has had its opportunity to form basically all of them into conventional adults.
That first track Bombtrack and then Killing In The Name and that was it, I was hooked.
