Vulgus Illustrata

Insidius is a death metal band from Olsztyn, Poland, active since 2012. Fusing old-school aggression with technical precision and blackened intensity, their sound channels the cold, relentless spirit of Polish extreme metal.Their 2016 debut Shadows of Humanity introduced a raw, no-frills attack. 2018’s Infamia (Ermland Productions) brought deeper atmospheres and sharper songwriting, earning them wider recognition. After years of touring and growth, the band returned to Heinrich House Studio to record their third full-length. Titled Vulgus Illustrata, the album drops in fall 2025—eight tracks of razor-sharp, blackened death metal featuring guest appearances by Piotr “Peter” Wiwczarek (Vader) and Moyses Kolesne (Krisiun).
