Efermus/Night's Threshold-Split

A slow but steady descent into psychosis and the darkest realms of the mind, with barely audible percussion, only some ghoulish rumbling beneath the droning dissonance and acidic murderous textures excreted from the guitars, drowning in grime and cadaverous slime. The tormented sounds of a soul upon which light has never shone.
Something to be surely appreciated by adepts of the most fetid realms of the underground, with acts like Rainha Cólera, Mallitiae or even Stalaggh
