I just read your post, I eccanta the subject, well you mainly refer to a fragment of the anti-establishment music that was made in Britain.
I think that if we look at the music anthropologically it has always been anti-sableciemiento, minstrels and troubadours are a good example of criticism of the monarchic system of its time.
I think that the 60's and 70's were undoubtedly the golden years of anti-establishment music, for example in South America there was very good production, to name a few musicians and bands, Los jaivas, Alí primera, Violeta parra, intillimani among others. who surprised with criticisms of the establishment of their countries of origin and also anti-imperialists.
and jumping a little in the 90s until today, because you already named legendary bands from the 80s, anti-establishment production continued to emerge. for example Spain has a very good punk and hardcore move, even Oil among those bands I can cite the cock records and some current as School of Hatred (this is very good) and Ska-p very listened to throughout Europe despite being in Spanish.
In the United States also emerged some groups with a style a little abstract but in itself with a digestible code for youth, such as Tool, burial, panther to name a few, even if we stop in 2018 I recommend two Chilean rappers one called Spokesman and another called Subverso are eminent in anti-establishment music.
I think the problem is that it became trade and currently despite the harsh criticism that may have a group the establishment knows how to numb the masses if they come to reveal against the power.
(Rage against the machine) another American band of the nineties considered as the first communist band in the United States became a highly consumed commercial product.
so at this point I think that after the Hippies the record companies understood that any social movement that expressed itself artistically against establishment through music could take advantage of it commercially and lead the industry in that way.
Clearly there are more groups that I consider as junk music, especially Latin productions such as reggaeton or Latin trap that the only thing they profess in their lyrics is sexual aberrations, drugs and denigration of women.
I can assure you that if shakira played in the 90s pop rock now plays reggaeton because it is what the industry dictates and if those social upheavals return then the industry will surely change its format to sell protest music.
greetings, and thank you for sharing a topic that fills me a lot to talk about
peace and love
Thanks for your detailed and interesting comment @arrozymangophoto. I will look out for some of those Spanish bands. I definitely think there is still good anti-establishment music around - it just doesn't get played on the radio so much these days, so it's good to hear these names.
I TOTALLY agree with this!
