MMXVII - MMXVIII combines two EPs from Abyssal Vacuum, the one from 2017 and the other from 2018."Abyssal Vacuum reveals a distinctive musical vision and 'voice', offering a conception of black metal that manages to be both mesmerizing and strikingly intense. Emanations from a deep and cavernous abyss, 'like exploring the darkest caves of Earth', but the experience it creates might also bring to mind the mysteries of the cosmos lurking in a hostile off-world void." -no clean singing"This project is a thick wall of black hate that is far more powerful than much of what you're hearing today. Abyssal Vacuum is a project that needs to be respected because it's that f***ing good!" -cvlt nation
