It's true, darkness wasn't even invented until Infester thought it up and then decided to record this demo and then show it to the world in the tender year of 1992. Two years before they would reach the deepest degraded depths of doomed up death metal they made this roughly recorded set of songs which is just as gruesome and grim as the crude cover art suggests. With it, they brought a new breed of patented slime riffs, logic scorning drums, invasive bass, and one of the most unhinged vocal performances in death metal.
Seriously though, it sounds like his diaphragm is gonna tear out and splurt right up and out of his mouth at times; he reaches worrying lows such as at the start of "Afterbirth... the meal" where his craving for some nice and healthy fresh placenta erupts into an rambling echoed gurgle over the crunchy riffs, as well as tortured animalistic wails in the vein of Lord Worm like just before the climax of title track “Darkness Unveiled”. The vocals wander in and out of the songs in a mix of incoherence and restraint which allows the band to show off their darkness in riff form.
Infester's riff arrangements are something to behold, they've got bone crunching Incantations, doom tinged Autopsies, and even the odd Bolt Throwing straight up power-chord flex throughout all four of the songs, always weaving in and out of different tempos with ease. Typically rough production provides a masochistic mindscrape of sound where the bass lurks like a burbling beast beneath the surface ready to spew up maddening grooves at any time, erupting most noticeably on the Best Advice From A Song Name Award winner "Open the Vein" where it dictates the song like a really cool demon slavering orders at his underlings before severing the song entirely right and watching it bleed out with a top notch dismal death groove.
One thing death metallists sometimes forget when they're trying hard to be all doom and gloom is to make songs actually sound good but Infester have got plenty of hooks reaching like claws from the yearning abyss to drag your forfeit little soul into it. Just try not retching up your guts along to the psychotic refrain of "DARKNESSSSSSSS... UNVEEEILED" or going into a riff induced vegetative state in the slow crescendo of intensifying riffs in "Afterbirth... the Meal".
Most people reading this will already have heard the band's classic and only album To the Depths... and it goes without saying if you want more murky odes to darkness get this thing and then listen to it.
