Children of Bodom has always been treated as a work solely of frontman Alexi Laiho. His vocals and guitar theatrics and songwriting dominate each of the band's releases, and "Halo of Blood" is no different. But behind Laiho stands one of the most talented bands working in metal today; adaptable, versatile, heavy, melodic, anything they need to be. Hidden in the shadows of CoB stands Henkka Seppälä, bassist and generally amiable guy. In search of his story, we sat down recently as Mayhem Fest.
