Death/doom, sometimes written as death-doom or deathdoom, is an extreme subgenre of heavy metal. It combines the slow tempos and pessimistic or depressive mood of doom metal with the deep growling vocals and double kick drumming of death metal. The genre emerged in the mid-1980s and gained a certain amount of popularity during the 1990s, but had become less common by the turn of the 21st century. In turn, death/doom gave rise to the closely related genre of funeral doom as well as to the more melodic and romantic gothic metal. The death/doom genre originated in the mid-1980s when the early progenitors like Dream Death began to mix traditional doom metal with the sounds of thrash and the nascent death metal scene. Early records by such bands as Paradise Lost, My Dying Bride and Anathema combined the sounds of mid-1980s Celtic Frost and Candlemass with the use of female vocals, keyboards and, in the case of My Dying Bride, violins.
