What is the music played by the Norwegian band Aeternus a subgenre of?
Death metal Death metal is an extreme subgenre of heavy metal music. It typically employs heavily distorted and low-tuned guitars, played with techniques such as palm muting and tremolo picking, deep growling vocals, aggressive, powerful drumming featuring double kick or blast beat techniques, minor keys or atonality, abrupt tempo, key, and time signature changes and chromatic chord progressions. The lyrical themes of death metal may invoke slasher film-stylized violence, religion (sometimes Satanism), occultism, Lovecraftian horror, nature, mysticism, mythology, philosophy, science fiction, and politics, and they may describe extreme acts, including mutilation, dissection, torture, rape, cannibalism, and necrophilia.
Electro-industrial Electro-industrial is a music genre drawing on EBM and post-industrial that developed in the mid-1980s. While EBM has a minimal structure and clean production, electro-industrial has a deep, complex and layered sound. The style was pioneered by Skinny Puppy, Front Line Assembly, and other groups, either from Canada or the Benelux. In the early 1990s, the style spawned the "dark electro" genre, and in the mid-/late-1990s, the "aggrotech" offshoot. The fan base for the style is linked to the rivethead subculture.
