Unsure if any are active or not, that isn't something I pay too close attention too personally unless it is local music, but here are a few recs from what I could Google about them being active (or at least not disbanding)
- Alcest
- Blut Aus Nord
- Sortilège (reformed in 2019 after a long hiatus)
- Bran Barr is good folk metal but only two albums though over 10 years, technically never disbanded.
- Amesoeurs (not active but still good)
- ADX if you like speed metal
- Attentat Rock (reformed in 08)
You think there is no authority in anarchist government? Have you ever read about horizontal-democracies?
Anarchist just means "against coercive authorities" namely "centralized and hierarchical governance"
You realize the fediverse that creates lemmy is an anarchist structure right?
