Acherontas
When it comes to ‘occult’ themes within the Black Metal scene, many countries might claim ‘courtesy’, but I guess Greece is one of those unnaturally-created eras (aka ‘country’) on Mater Terra that houses many ‘occult’ bands. And within quite an impressive list of bands worth mentioning (but I won’t enlist them, for it will distract from the essence, and since I am too lazy…), Acherontas cannot be denied / ignored at all.
