Unlike 'The Satanist', which was primarily recorded in one studio, 'I Loved You At Your Darkest' saw its production spread across Poland and the United States. It was produced by the bandmembers themselves, with drum co-production by Daniel Bergstrand (MESHUGGAH, IN FLAMES), mixing by Matt Hyde (SLAYER, CHILDREN OF BODOM) and mastering by Tom Baker (NINE INCH NAILS, MARILYN MANSON).

Which is to say nothing of the 17-piece Polish orchestra arranged by Jan Stoklosa and engineered by Tomasz Budkiewicz. Or as Nergal sums it up: "Pretty much every instrument was recorded in a different studio, and a lot of amazing people were involved."
