The five-piece, Helsinki based heavy metal band BEAST IN BLACK was founded by Anton Kabanen soon after he had parted ways with BATTLE BEAST in 2015. By the end of 2015 the band played their first gig as opening act for NIGHTWISH. The making of »Berserker« was already in progress back then and it was completed in summer 2017. A deal was signed with Nuclear Blast almost immediately after the completion of the album.
»Berserker« continues in the style of Anton's previously composed works which include the first three BATTLE BEAST albums. One of the essential themes on this debut album is the Japanese manga and anime »Berserk«.
