KMFDM! It's a German industrial rock/metal band. The full name (they really just go by the acronym now tbh) translates roughly to "no mercy for the majority". They're very political, especially emphasizing on anti-fascism.
They formed in the early '80s and are coming out with their 20-somethingth studio album this year, so I feel like their old but still current. (Although they're very much still "underground".)
Also, a lot of their songs are in English! (And the members aren't all German. They've gone through a lot of different members throughout the almost 4 decades they've been around.)
Here are a few of my favorites (under spoiler for length):
Lemme know what you think.

Going off on how you feel about KMFDM, I can give you some other music recommendations. iirc you're fairly versatile, so I think you'll like them!
