デスメタル
Death metal is an extreme sub-genre of heavy metal music that features fast, distorted, down-tuned, and sometimes palm-muted guitar instrumentation, growled and screamed vocals, and hyper-fast, blast beat drumming. Death metal lyrics typically feature graphic, sometimes pornographic and misogynistic, themes of violence, gore, disease, and death; Satanic, blasphemous, and anti-Christian content; or, to a lesser extent, war, apocalypse, social and philosophical concerns, and esotericism and spiritualism.
