A subgenre of heavy metal. Characteristics of black metal include typically high-pitched screaming vocals, tremolo picked guitars lacking bass and emphasising treble, and blastbeats (quadruple time drum beats). Unlike its sibling, the more thrash-based death metal, black metal concentrates more on mood and melodies (primal as they may be) instead of riffs and heaviness. The line between death and black metal can often be hazy, which is why categorizations are not really that important.
"Hmm, do I want to be mindless MTV-watching retard and buy a 50 Cent album, or a person who listens to good, well-composed, uncompromising music and buy a Dark Funeral CD."
Blastbeat originated in the '80s by hardcore and proto-grindcore bands which were seeking ways to bring the speed and harshness of their music to a new level. Popularized by grindcore bands such as Napalm Death and Carcass, the blastbeat eventually became an essential, if not the most important and distinctive feature of extrememusic.
