Some vetted black metal recommendations from me: Spectral Wound, Zeicrydeus, Marrow of Man, Summoning, Traktat

Edit: since my comment is getting some interest, I figured I could share the links:

Summoning - epic atmospheric black metal about Tolkien’s universe, Austria - this is the only recommended band here that is not explicitely leftist. One member is leftwing, the other is rightwing, but not far-right.

Zeicrydeus - unusual kind of black metal with hellenic influences about a fantasy universe, QC Canada

Marrow of Man - black metal with great song writing, Netherlands

Spectral Wound - black metal, QC Canada

Traktat - black metal with an antifascist theme, Germany
