For those who have never heard of this band, the distinction between black and death mainly depends on the musical atmosphere, whether it is eerie or violent. The former is generally black and the latter is generally dead. Secondly, it depends on the arrangement of RIFF. Dead repetition is usually more intense than black, and the second is whether the rhythm is high or slow, and death is generally faster than black, and whether it is a deep throat dead cavity or a shallow throat dead cavity (black cavity). Generally, only death (especially residual death) will occur. Shallow throat dead cavity and black cavity may appear in both black and spin death. In addition, only black people (especially symphonic black people) may have orchestral music and female high-pitched voices or choirs as embellishments, but just looking at the song title, the band feels like doomsday metal.
