Heavy metal genres
A number of heavy metal genres have developed since the emergence of heavy metal during the late 1960s and early 1970s. At times, heavy metal genres may overlap or are difficult to distinguish, but they can be identified by a number of traits. They may differ in terms of instrumentation, tempo, song structure, vocal style, lyrics, guitar playing style, drumming style, and so on.
Alternative metal
Alternative metal is a style of heavy metal and alternative rock which emerged in the mid-1980s and gained popularity in the early 1990s.Alternative metal usually combines heavy metal with influences from genres like alternative rock, and in some cases, other genres not normally associated with metal as well. One of the main characteristics of alternative metal and its subgenres are heavily downtuned, mid-paced "chug"-like guitar riffs. Alternative metal bands are also often characterized by melodic vocals, unconventional sounds within other heavy metal genres, unconventional song structures, and sometimes experimental approaches to heavy music. Many of the early alternative metal bands originated from Los Angeles. Prominent bands in this genre include Soundgarden, Alice in Chains, Faith No More, Helmet, Life of Agony, Rollins Band and Tool. More modern bands include Breaking Benjamin, Chevelle, Godsmack and System of a Down.
Subgenres of alternative metal
Funk metal
Funk metal is essentially a fusion of heavy metal and funk. It started off in the late eighties as a subgenre of alternative metal and was heavily influenced by bands such as Red Hot Chili Peppers and Fishbone. Funk metal bands often use a conventional riffing style influenced by 1980s thrash metal, unlike bands from other alternative metal genres. During the late-'90s, many bands which started out as funk metal branched out into more commercially viable genres, such as alternative rock and nu metal. Notable funk metal bands include Living Colour, Infectious Grooves, Mordred, Primus, and Rage Against the Machine. The biggest regional scene during funk metal's prime was San Francisco.Nu metal
Nu metal, also known as aggro metal, is a fusion genre that blends alternative metal and groove metal elements with other styles, including grunge, industrial, funk and hip hop. The nu metal builds on rap metal's rock and rap collaborations, but it highlights some of the more aggressive elements of its musical ancestors. Intense and angry lyrics, off-pitched guitars, and massively amplified beats are typical of nu metal songs. The style is mostly syncopated and based on riffs, and is influenced by groove metal rhythm. Some nu metal bands use seven-string guitars, which are sometimes down-tuned to increase heaviness, resulting in bass guitarists using five and six-string instruments. Turntables, sequencers and samplers are sometimes included. Nu metal vocal styles range between melodic singing, rapping, screaming and death growling. The Bakersfield-based Korn became the first band to be labeled as "nu metal". MTV states that Korn "arrived in 1993 into the burgeoning alternative metal scene, which would morph into nü-metal the way college rock became alternative rock." Coal Chamber, Limp Bizkit, Linkin Park, Slipknot, Papa Roach, Kittie and Disturbed are prominent bands in this genre.Rap metal
Rap metal bands institute the vocal and lyrical form of hip hop. Examples of rap metal include Crazy Town, Clawfinger, Stuck Mojo, Skindred and Rage Against the Machine. The thrash metal band Anthrax also helped pioneer the genre. Rap metal is often mislabeled as rapcore or nu metal, a genre which has similar elements in the music, rap metal usually does not include turntables or sampling into its sound, although keyboards are often used. Rap metal bands, unlike nu metal bands, are almost always fronted by rappers. Rap metal also lacks the melodic singing and growling commonly associated with nu metal.Avant-garde metal
metal or avant-metal, also known as experimental metal, is a subgenre of heavy metal music loosely defined by use of experimentation, and characterized by the use of innovative, avant-garde elements, large-scale experimentation, and the use of non-standard and unconventional sounds, instruments, song structures, playing styles, and vocal techniques. It evolved out of progressive rock, jazz fusion, and extreme metal, particularly death metal. Some local scenes include Los Angeles and the San Francisco Bay Area in the United States, Oslo in Norway, and Tokyo in Japan. Pioneers of experimental metal include Boris, Celtic Frost, Earth, Helmet, Maudlin of the Well, Neurosis, Sunn O))), and Voivod.Black metal
Black metal is an extreme subgenre of heavy metal. Similarly to avant garde metal bands, black metal singers and groups also feature unconventional song structures and lyrical emphasis on atmosphere. Common traits include fast tempos, shrieked vocals, highly distorted guitars played with tremolo picking, blast beat drumming, raw recording, and unconventional song structures.During the 1980s, several thrash metal bands formed a prototype for black metal. This so-called "first wave" included bands such as Venom, Bathory, Mercyful Fate, Hellhammer and Celtic Frost. A "second wave" arose in the early 1990s, spearheaded by Norwegian bands such as Mayhem, Burzum, Darkthrone, Immortal, and Emperor. The music of the early Norwegian black metal scene became a distinct genre.
Initially considered a synonym for "Satanic metal", black metal has often been met with hostility from mainstream culture, mainly due to the misanthropic and anti-Christian standpoint of many artists. Moreover, several of the genre's pioneers have been linked with church burnings and murder. Some have also been linked to neo-Nazism; however, most black metal fans and most prominent black metal musicians reject Nazi ideology and oppose its influence on the black metal subculture.
