Inspired largely by the lumbering dirges and stoned, paranoid darkness of Black Sabbath, doom metal is one of the very few heavy metal subgenres to prize feel and mood more than flashy technique (though the latter can certainly be present). Even more indebted to Sabbath than most metal, doom metal is extremely slow, sludgy, and creepy, feeling so heavy it can barely move; its deliberate pace and murky guitars are meant to evoke (what else?) a sense of impending doom. The movement began to take shape in the mid-'80s, as underground bands like the SST label's Saint Vitus, the critically acclaimed Trouble, and Sweden's Candlemass attracted cult audiences for their out-of-fashion, Sabbath-dominated sounds.
