Black metal: Due to historical reasons, religion, as a dominant ideology, occupies a very important position in the West. However, due to its terrible bondage to human nature and suppression of life instinct, some anti-religious philosophical thoughts have appeared in the history of western culture. However, whether they are primitive black metal or philosophical anti-religious thinkers, their starting point of opposing Christianity is very similar-abolishing the excessive restrictions of religion on human nature, so that human potential and nature can be naturally displayed. In other words, anti-religion (mainly anti-Christianity) is to make people live more naturally and "let the will of life show its power more freely". Similarly, black metal advocates returning to nature, just like an ancient primitive religion. So we can often see that the lyrics of excellent black metal music are full of philosophical thinking.

Besides these, many excellent black metal bands have a common feature, that is, they criticize the decadent signs of modern civilization, yearn for primitive nature or ancient civilization, fear natural life and rebel against authoritarian religions. I think this is why many bands choose to use some magnificent natural scenery as the album cover, rather than some bluffing and evil pictures.

However, many so-called ferrous metals have already deviated from these. They are anti-religious in order to believe in Satan. From believing in God to believing in Satan, I still crawl at the feet of different gods. Evil clothes and music are just a vent or gesture.

As an extreme heavy metal music, death metal is more about expressing anger and exposing the darkness, ugliness and selfishness of human nature. Death metal came from thrash metal in the late 1980s. With blunt lyrics and morbid obsession with flogging, I took an extreme route.

Death metal-as the name implies-is only related to death, pain and suffering. these

Cruel and cold lyrics are constantly noisy and repetitive. This style is influenced by many slow metals like Black Sabbath, and Metallica is a typical example.
