Mercyful Fate is a Danish heavy metal band from Copenhagen, formed in 1981 by vocalist King Diamond and guitarist Hank Shermann. Influenced by progressive rock and hard rock, and with lyrics dealing with LaVeyan Satanism and the occult, Mercyful Fate was part of the first wave of black metal in the early to mid-1980s, along with Venom and Bathory. The band is also cited as a formative influence to the then-nascent genres of thrash metal and death metal, as well as the Norwegian black metal scene.
