Taking major influence from Bathory and Venom, the ganre became largely associated with Norway through the work of Mayhem, Burzum and Dark Throne, many of the later bands categorised into the black metal genre being influenced by these three bands, and many of these bands being from Norway themselves.
Spawning from thrash metal as black and death metal did, they ran parallel. Eventually the two genres became commonly associated since they both implemented tremelo picking, blast beats, and invariably screamed vocals much of the time. This was taken into influence by some bands and the genres eventually interweaved with some projects such as Dark Throne, Profanatica, and late Emperor.
Other movements of the genre since its rising in the Norwegian metal scene have been melodic/symphonic projects such as Cradle of Filth and Dimmu Borgir, and more underground movements such as the Black Legions, which as a collective are as yet universally nameless.
It is inspired by bands such as Venom and Mercyful Fate. And the first Black Metal band is debated to be either Bathory or Celtic Frost. Although these were unrefined and were not the original true Black Metal bands. The first real Black Metal was started in Norway by bands such as Mayhem, Emperor, Darkthrone, and Satyricon. Later many other sub-genres of Black Metal were created.
Black Metal is usually definied by Vocals that are high in tone and pitch and are usually refered to as the 'Black Metal Screech', very different from the Guttural sound of the 'Death Metal Growl'. Lyrics mostly have Anti-Christian, Misantropic, Satanic, Luciferian, and Pagan basis. Drum beats described as 'blast beats'. But are different from Death Metal blast beats because there is more focus on the Snare drum instead of the Toms. The guitars are usually very repeatative and the riffs are usually only four to five chords. The basslines are similar to the guitar riffs but usually have a more punk quality to them. And the quality of the recordings is usually very bad.
Black Metal was started in defiance of the Death Metal scene, instead of having great, clean production, Black Metal had low and piercing quality. Instead of having complicated riffs and beats, BM had a more simplistic approach. And BM strived to be more controversial in lyrical themes.
Black Metal IS a harsh, noisy offshoot of Thrash Metal based around Satanic ideals and Norse Mythology that came into being in the early 80's in Norway. Black Metal can be dissociated from Thrash Metal by its high-pitched unnatural screams made to sound demonic, its use of Blast Beats (32nd-note snare hits), syncopation, and costume (Corpse Paint, which is black and white make-up used to further enhance the demonic quality and hide the identity of the wearer). Band members also go by fabricated names.
The reason Black Metal revolves around these things is because it opposes the early Norwegian invasion of Christianity (which was brought by their own King Olaf in early A.D., not by missionaries as some think). Black Metal uses a pseudo-Grotesque method to offend society in their live shows, while simultaneously attracting listeners to the cause, with their use of Corpse Paint, blood and gore, and mock crucifixions that some bands put on during live concerts. Some of its scene members have burned churches. It is not a joke, except to some, who would like to pass it off as harmless. This is the REAL difference between a true Black Metaller and a poser.
Black Metal bands use terrible production in their records o...
First Wave of Black Metal (aka Old School): A lot of similarities with Thrash Metal, but the Black Metal is obvious.
Second Wave of Black Metal: Modern-sounding BM.
Black Metal: There is no point in redefining it, since virtually every definition above this, has been dealing with that particular style of BM.
Raw Black Metal: usually very monotonous, unmelodic, with very bad production, and cheaply printed releases.
NSBM: Stands for Nationalist Socialist Black Metal. Is defined by the lyrics, as opposed to music. Lyrics usually deal with various forms of nationalism, racial supremacy, and hate. Often also incorporates such themes as paganism, and the war against Judeo-Christianity.
Folk Black Metal: Any Black Metal with folk melodies or instruments used. Sometimes deals with the same concepts as NSBM.
Viking Black Metal: Any Black Metal with lyrics about vikings. Sometimes uses folk elements.
Symphonic Black Metal: This form of BM is very far from the origins of the genre, often sounding like extreme metal (as opposed to BM), it is uncommon for bands in this category to use an orchestra, or separate orchestral instruments.
Un-Black Metal: Any Black Metal dealing with Christianity (in a positive manner).
Death/Black: There is no uniform definition of that, but basically anything that uses elements of death and black metal together.
There are various less-widespread forms of Black Metal, such as a mixing BM...
