Blood Fire Death is the fourth studio album by Swedish extreme metal band Bathory. It was released on 8 October 1988.. The album, although mostly black metal, includes some of the first examples of Viking metal.

those who are new in the field and that I'm approaching or even for those who may need further clarifications:Viking Metal is an evolution of black metal starting from the voice, whose singing technique is at random method; in the case of Bathory there's an abandonment of the true and just scream with the adoption of a very dirty world, but slowly lends to clean female vocals
