Excellent experimental, symphonic dark metal with elements of death/doom (in terms of growls occasionally used). Full length album by this U. S. band that is very promising and keeps things interesting with plenty of ideas. Recommended release that consumes your senses. Beautiful obscure melodies.

Catacomb(Fra) - Morbid Attraction demo 1991.

Old school French death metal with the first demo Morbid Attraction. This is a bit amplified demo than the one posted at raf666 blog, cause it suffers in loudness. It's decently loud this time. Complete obscure, underground monster to be expected here.
Stay in the grasp of darkness with Catacomb.

Astaroth(US) - Drowning In Blood (demo 1992).

From the deepest bowels of Hell this demon has found itself resurfaced here. Incredible heaviness and tight bass overwhelming sound turns your bones to ash. One of the sickest demos i've heard in a while. Astaroth concentrate themselves on this demo to create an atmosphere of doom and soul devouring death metal. This demo will almost certainly make you drown. Highly recommended!!

A mighty band from Belarus. With themes of death and religion present in their lyrics, this band plays old school death metal in its purest form. A demo dating back to '92, carries the title Resurrected. Rare and valuable release from Exhumator.

Sick and disturbing collaboration of Italian and Czech members in this filthy, raw sludge/drone doom metal band. This post features two demos by Cervix. Really twisted shit.

Ancient underground blackish speed metal band from Italy, in form of only one track i could find from 1983.
So great stuff existed back then too.
