Punk was a musical big bang of a sort. I spend most of my time in adjacent subgenre. Most people do without realizing it honestly. Postpunk, goth, new wave, alternative, and industrial all descend from it. As well as other genera like ska, psychobilly, and horror punk. Though I'd argue that a lot of the political sentiment today is in industrial and EBM. Alec Empire and Atari Teenage Riot 20 years ago were suuuper political. I mentioned KMFDM elsewhere, they go way way back to the early 80s. Even Trent Reznor and nine inch nails, very political. Even male model Marc Massive and his group Massive Ego. Really continues the political and social commentary.
