In the last two decades, a bizarre and violent musical subculture called "Black Metal" has emerged in Norway. Its roots stem from a heady blend of horror movies, heavy metal music, Satanism, Paganism, and adolescent angst. In the early-mid 1990s, members of this extremist underground committed murder, burned down medieval wooden churches, and desecrated graveyards. What started as juvenile frenzy came to symbolize the start of a war against Christianity, a return to the worship of the ancient Norse gods, and the complete rejection of mainstream society.

The religious ferocity of Heavy Metal fandom is one of the most fervent in the history of subculture. The display of this fervor has been channeled and distilled throughout time into one sacred object: the battle vest. Often referred to as the Kutten (German for monk's robe), the battle vest serves a multitude of purposes: as a musical CV, a badge of authenticity, a creative practice of identity, and a fashion statement. Defenders of the Faith documents the timeless and universal concept of fandom through the elevation of the battle vests, revering them beyond the sweaty bodies they adorn and the pits they live in, to the status of religious artifact. Photographer Peter Beste has been documenting subcultures for over 20 years. His first book True Norwegian Black Metal (Vice Books) was a portrayal of the extreme end of the genre and the stunning photos contained within translated far beyond the niche fans of the music, selling tens of thousands of copies. His critically acclaimed follow up book Houston Rap showed his breadth as a photographer and Juxtapoz called it "An astonishing and important insight into a great American cultural narrative." Defenders of the Faith is Beste's fourth book that has been edited by Boo-Hooray's Johan Kugelburg and his photographic treatment of traditional heavy metal culture and dress code is similarly striking. Metal fans, fashion enthusiasts, and subculture geeks will come to the book naturally but the images have a gravity of humanity that speaks to universal expression of passion and devotion and make the book instantly relatable. Heavy Metal has survived and evolved through the decades, always maintaining a deep connection with its audience. The decorative armor of the battle vest serves as a visual history of the genre, memorializing the bands and also telling a personal story of each fan. This collaborative nature has always been at the heart of metal, elevating the individual and the communal beyond the dynamic of performer/audience. As Peter Beste put it himself, "For many, it shows how "true" one is by how authentic their patches are, which festivals they have attended, or which bands you got to see way back when. It is an object that gains in value as it deteriorates, and is pretty much never bought or sold. You have to create your own." Recognizing these personalized artifacts as timeless and artistic expressions of the universal human experience of devotion helps shed light on metal's place within our cultural history.
