Steeped in foreboding mythology, the dark underbelly of heavy metal ignites debate to this day. Guitars playing abrasive, discordant riffs, the thunderous double-kick of the drums acting like an accelerated heartbeat, and porcine, guttural vocals pummeling twisted lyrics. Courting controversy from inception to its modern day iteration, death metal presents a number of contradictions: Driven and adventurous musicians compete to make uncomfortable noises; it is crude and far beyond parody and yet consistently popular; and the music is pig-headedly uncommercial despite making a few labels, albeit briefly, wealthy. This book explores the history and methodology of the genre, charting its aims and intentions, its crossovers to the mainstream, successes and failures, and tracks how it developed from the bedrooms of Birmingham and Florida to the near-mainstream, to the murky cult status it enjoys today.
