The Argentine heavy metal is a heavy metal music movement that originated in Argentina in the 1980s.
 The first popular artist was Pappo, who created the band Riff influenced by the contemporary new wave of British heavy metal.
 V8 was formed at that time as well, and most of its members created notable bands after their respective departures from the band: Ricardo Iorio and Walter Giardino, currently in Almafuerte and Rata Blanca, are still popular.
 The second half of the 1980s saw the success of hard rock bands such as Kamikaze, Alakran and Rata Blanca, with an aesthetic similar to the contemporary glam metal.
 Thrash metal bands, such as Hermética, Horcas and Lethal, appeared in the early 1990s.
Chinese heavy metal (中国重金属, pinyin: "Zhōngguó Zhòngjīnshǔ"; also 中国重金属音乐, "Zhōngguó zhòngjīnshǔ yīnyuè", literally "Chinese heavy metal music") is commonly used to describe a wide variety of forms of heavy metal music, in connection with the rock bands and solo artists from native Chinese-speaking regions (including Mainland China, Taiwan, Hong Kong, Macau, etc.).
 Typically, Chinese heavy metal bands adhere to one subgenres of heavy metal such as death metal, thrash metal, and power metal, but commonly using Chinese-based lyrical content rather than English.
Canadian heavy metal music has a long history.
 Going back to the late 1960s, Canada has produced metal bands that have and continue to influence metal bands to this day.
 In 1964, Toronto-based band The Sparrows was formed.
 This band later changed their name to Steppenwolf and featured Canadians John Kay, Goldy McJohn and Jerry Edmonton.
 Steppenwolf's 1968 single "Born to be Wild" was the first use of the words 'heavy metal' in a song's lyric.
 In 1970, Woodstock, Ontario based Warpig released their metal music debut, which, although never reaching mainstream success like fellow heavy metal bands Black Sabbath and Blue Cheer, has become a cult favourite within the Doom metal scene.
Kekal (sometimes stylized as KEKAL) is a heavy metal and electronic music band formed in 1995 in Jakarta, Indonesia.
 According to AllMusic, Kekal was one of the first heavy metal bands from Indonesia to make international inroads, and according to sociologist of heavy metal, Keith Kahn-Harris, was one of the few extreme metal bands from Southeast Asia to ever make more than a minimal impression on the global scene.
 Founded by two musicians known simply Yeris and Newbabe, the band underwent some shifts in lineup in its early years, but emerged with a consistent lineup of three key-members, guitarist/vocalist Jeff Arwadi, bassist Azhar Levi Sianturi, and guitarist Leo Setiawan.
 Frequently labeled as black metal, progressive metal, and avant-garde metal, Kekal plays a very diverse range of music styles within the frame of metal and rock, incorporating many other music genres such as ambient, electronic, jazz fusion, and progressive rock.
 Over the course of its career, Kekal has transitioned from a heavy metal-based style to a more experimental and electronic sound.
This is a list of gothic metal bands.
 Gothic metal is a genre of heavy metal music.
 It is characterized as a combination of the dark atmosphere of gothic rock with the aggression of heavy metal music.
 The genre originated during the early 1990s in Europe as an outgrowth of death/doom, a fusion of death metal, doom metal, and gothic rock.
 The music of gothic metal is diverse with bands known to adopt the gothic approach to different styles of heavy metal music.
 Lyrics are generally melodramatic and dark with inspiration from gothic fiction as well as personal experiences.
X Ambassadors (also stylized XA) is an American rock band from Ithaca, New York.

 The band's debut full-length album, "VHS", was released on June 30, 2015.
Heavy metal lyrics are the words used in songs by heavy metal artists.
 Given that there are many genres of heavy metal, it is difficult to make generalizations about the lyrics and lyrical themes.
 In 1989, two metal scholars wrote that heavy metal lyrics concentrate "on dark and depressing subject matter to an extent hitherto unprecedented" in any form of popular music.
 Jeffrey Arnett states that metal songs are "overwhelmingly dominated" by "ugly and unhappy" themes which express "no hope" for the future.
 Deena Weinstein has proposed one way to analyze metal song themes is loosely grouping them into two categories: the Dionysian theme (a reference to the Roman God of wine), which celebrates "sex, drugs and rock and roll", partying, and enjoyment of life and the Chaotic theme, which involves dark subjects such as Hell, injustice, mayhem, carnage and death.
 Not all metal genres fall into Weinstein's two theme model; for example power metal's lyrical themes often focus on fantasy and mythology, camaraderie and hope, personal struggles and emotions, among other themes.
 Another exception is pop metal bands, which replaced "gloom and doom" themes with "positive, upbeat" songs about romantic love and relationships, part of their goal of appealing more to female listeners.
 In metal overall, the small number of metal songs about relationships are typically about unions that have "gone sour" long ago.
South African heavy metal has its roots in South African hard rock and heavy metal bands in the 1980s.
 Through the late 1980s and the early 1990s South Africa grew a well supported metal scene.
 Particular scenes developed in Cape Town, Johannesburg and Pretoria.
 South African heavy metal has been particularly influenced by foreign bands, particularly the New Wave of American heavy metal and American thrash metal.
Bullet for My Valentine, often abbreviated as BFMV or B4MV, are a Welsh heavy metal band from Bridgend, formed in 1998.
 The band is composed of Matthew Tuck (lead vocals, rhythm guitar), Michael Paget (lead guitar, backing vocals), Michael Thomas (drums) and Jamie Mathias (bass guitar).
 Former members include Nick Crandle and Jason James; both were on bass.
 They were formed under the name Jeff Killed John and started their music career by covering songs by Metallica and Nirvana.
 Jeff Killed John recorded six songs which were not released; two of these tracks were reworked later in their career as Bullet for My Valentine.
 Financial difficulties dictated the name change, which was followed by a change in music direction.
 In 2002, the band secured a five-album deal with Sony BMG.
 The band has stated that their music is influenced by classic metal acts such as Metallica, Iron Maiden and Slayer.
 The band is part of the Cardiff music scene.
This is a list of power metal bands including notable bands that have at some point in their careers played power metal or heavily contributed to the genre's development.
 Power metal is a subgenre of heavy metal music combining characteristics of traditional metal with speed metal, often within symphonic context.
 Generally, power metal is characterized by a more uplifting sound, in contrast to the heaviness and dissonance prevalent in styles such as doom metal and death metal.
 Power metal bands usually have anthem-like songs with fantasy-based subject matter and strong choruses, thus creating a theatrical, dramatic and emotionally "powerful" sound.
 Power metal has two distinct early styles, which developed in parallel.
 US Power Metal was developed in the mid/late 80s, pioneered by bands such as Omen characterized by harsh thrashy sound and a focus on speed and soaring operatic vocals.
 It was directly influenced by speed metal and NWOBHM, and had a drop in popularity in the 90s.
 European Power Metal was developed in the late 80s by key bands such as Helloween, and was more melodic, employing keyboards, synths and anthem-like songs.
