Yeah, not too shabby..
Not particularly a fan of Venom, though the influence remains quite clear.
Killer guitar solo! A decent romp overall.
I'd take a shot at this being between 82-84 in which case Hellhammer certainly has the 'edge', yet it's always good to hear worthy shit that has been Buried by Time and Dust.
Not black metal but check out The Faceless. They make futuristic death metal. Great band. Another band I'd recommend is Gigan and their record Quasi-Hallucinogenic Sonic Landscapes.
Well, I gave The Faceless - Planetary Duality (album) a listen. Cheers for the recommendation, I'm not into a lot of Modern Bands at all though I didn't mind this stuff.
Should you find the time and are not already familiar with, some bands from my neck of the woods to check out:
StarGazer- A Merging to the Boundless
Vassafor- The Obsidian Codex
Temple Nightside - Condemnation.
Those last two are deep and dark as the yawning abyss.
Stargazer contains the more esoteric, irregular passages, to be found among their many varied influences.
