Ideology

Any attempt to lay out the ideology of a musical genre is bound to generalize to the extent that some traits are unfairly emphasized, while others are laid out which do not apply to all. Nonetheless, black metal is generally opposed to Christianity and supportive of individualism. Arguably, this is the only coherent sentiment among black metal artists. In a Norwegian documentary, Fenriz stated that "black metal is individualism above all". Artists who oppose Christianity tend to promote atheism, antitheism, paganism, or Satanism. Some musicians – such as Euronymous, Infernus and Erik Danielsson – have insisted that Satanism should be foremost. Occasionally, artists write lyrics that appear to be nihilistic and misanthropic, although it is debatable whether this represents their mentality. In some cases, black metal artists have also espoused romantic nationalism, although the majority of those involved are not outspoken with regard to this. Nonetheless, many black metal artists seek to reflect their surroundings within their music. The documentarist Sam Dunn noted of the Norwegian scene that "unlike any other heavy metal scene, the culture and the place is incorporated into the music and imagery".
Regarding the sound of black metal, there are two conflicting groups within the genre – "those that stay true to the genre's roots, and those that introduce progressive elements". The former believe that the music should always be minimalist – performed only with the standard guitar-bass-drums setup and recorded in a low fidelity style. One supporter of this train of thought is Blake Judd of Nachtmystium, who has rejected labelling his band black metal for its departure from the genre's typical sound. A supporter of the latter is Snorre Ruch of Thorns, who stated that modern black metal is "too narrow" and believes that this was "not the idea at the beginning".
Some prominent black metal musicians believe that black metal does not need to hold any ideologies. For example, Jan Axel Blomberg said in an interview with Metal Library that "In my opinion, black metal today is just music." Likewise, Sigurd Wongraven stated in the Murder Music documentary that black metal "doesn't necessarily have to be all Satanic, as long as it's dark."
