The band is considered a pioneer of the Nordic European Christian Extreme Metal scene and has had a significant influence on the genre with their 1991 demo "The Defeat of Satan." This specialized book details the band's development, their musical influences, and the cultural contexts in which they operated. Notably, Antestor is the only Christian band to have released an album with Cacophonous Records, a label also known for other prominent bands such as Dimmu Borgir and Cradle of Filth.
