The origin of satanic heavy metal, which eventually assumed the title of "black metal," is most commonly linked to the British trio, Venom, who bestowed the name upon the subgenre with the title of its second album in 1982. In the decades since, black metal has undergone several periods of evolution, which have often been cultivated in self-contained, stylistic incubation regions in different parts of the world. In retrospect, one unlikely context of this sort was Poland in the early 1980s, which was dominated by pro-communist martial law, and from which the band Kat somehow emerged. Kat's role in the development of black heavy metal is one that is typically overlooked, but it is one of significance that deserves proper recognition. Kat's musical direction became increasingly focused on themes related to satanism, murder, and vampirism, among others of the same ilk. This confluence of events would therefore result in Kat's role as a pioneer in the development of the black heavy metal subgenre. "666," was recorded with Polish lyrics with a production that seems to recreate the setting of a cavernous medieval torture chamber. This, of course, is appropriate, given the fact that the band's name translates to "Executioner" in English. Most tracks flourish in the mid to upper tempos of metal from the era, a characteristic which lends itself well to the effect the band intended to nurture. The culmination of Kat's formative years as expressed in "666" is one that has left an indelible mark on black metal's historical trajectory, not only in Eastern Europe, but in the world at large.
