Death Metal
One of the more extreme forms of metal, death metal is basically an offshoot of thrash, with less melodic riffs and a low, growly, often almost unintelligible vocal style that at its best (or worst, depending on one's point of view) has been described as "cookie monster vocals". The early nineties saw the initial rise of death metal in places such as Florida ( Death, Morbid Angel, Deicide, Obituary, and others) and Sweden ( At The Gates, Entombed, and others), and remains a dominant form of extreme metal to this day.
