RABM or Red & Anarchist Black Metal: all kinds of black metal-related music charged with radical leftist (anarchist, libertarian socialist, eco-anarchist, etc.) political views. Some of the bands featured here may be not openly political, but all of them are RABM-friendly;
- blackened crust/hardcore/punk (only if it's openly RABM-friendly, or if it's just very good music; we have no intention to collect here all the blackened punk in existence);
- other kinds of political (anarchist, socialist, etc.) metal - death, thrash, post-metal, etc.;
- dark ambient, neofolk, industrial, dark electro, etc. - but only if it has some RABM-friendly ideology;
- regular punk/hardcore/crust, post-rock, conscious hip-hop, etc. - but only as a rare exception (so if you want to send us a demo in one of these genres, you're probably in the wrong place).
