What is philosophy of black metal?

Black metal is a very extreme subgenre of heavy metal, originating in the late 80's in several countries (venom England, bathory, Sweden, and Celtic frost , u.s.a) Black metal got its name from the song "Black Metal" by Venom off the album of the same name. Early Black metal took its look from Celtic Frost, Sound from Venom and harshness from Bathory.

The second wave of Black Metal started in Norway with the band Myhem. The modern

Black metal sound was created by the bands Mayhem and Burzum. They made their music as a more extreme pursuance of metal and as a direct affront to Christianity, specifically Catholicism.

Most musicians in black metal are Satanists, although there have been several musicians in black metal who were druids, Atheists, Agnostics, heathens, Stoics, etc.

In black metal the ideology behind the music is very important. The black metal band gorgoroth refuses to release their lyrics to the public lest they affect someone's interpretation of the music.

Black metal is characterized by fast strumming of all six strings on an Electric Guitar, highpitched screaming vocals, lyrical content encompassing, Satan, Satanic Rites, Satanism, hate for Christianity, hate for Christians, killing Christians, ancient rites of killing Christians, suicide, S&M fetish, burning Churches, black metal, hell, depression, and other such cheery subject matter.

Quite possibly the greatest examples of black metal are

Carving a Giant by Gorgoroth

The First Cut is the Deepest by Carpathian Forest

A Dying God Coming Into Human Flesh by Celtic Frost

Spell of Destruction by Burzum

inno a Santana by Emperor

Current bands that are lumped into the Black metal sound are not true Black Metal in the very sense that they are more orchestrated and keyboard driven, These "Symphonic Black Metal Bands" are true to the satanic ideology, but not the raw, grim sounds of second and first wave Black Metal
