List of avant-garde metal artists: This is a list of avant-garde metal artists, regional scenes, and record labels.  Avant-garde 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 and various forms of metal, including extreme metal, particularly the extreme subgenre death metal.  Some early examples are the King Crimson releases "Larks' Tongues in Aspic" and "Red" in 1973 and 1974 respectively, and the 1976 Led Zeppelin album "Presence".  The genre emerged in the early 1980s through the efforts of bands such as Celtic Frost and Voivod, who pioneered the genre.  Other pioneers of avant-garde metal include Boris, Earth, Helmet, maudlin of the Well, Neurosis, Sunn O))), and Mr. Bungle.  In the late 1990s, Misanthropy Records emerged as a promoter of Norwegian avant-garde metal until it folded in 2000, and, according to Jeff Wagner, in the late 1990s and early 2000s, a so-called "new wave of avant-garde metal" was spearheaded by The End Records.  Some other record labels which promote avant-garde metal are Aurora Borealis, The Flenser, Holy Records, Hydra Head Records, Ipecac Recordings, Napalm Records, the Relapse Entertainment imprint of Relapse Records, Seventh Rule Recordings, and Southern Lord Records.  In the United States, local avant-garde metal scenes have emerged in the San Francisco Bay Area, with bands such as Giant Squid, Grayceon, and Ludicra, Boston, with bands such as Isis, Kayo Dot, and maudlin of the Well and Seattle.  According to the "New York Times", some regional scenes that developed in the mid-1990s included the cities of Tokyo, Los Angeles, and Oslo.

List of metalcore bands: Metalcore is a broad fusion genre of extreme metal and hardcore punk.  Its subgenres include mathcore and melodic metalcore.  This incomplete list includes bands described as performing any of these styles, including those who also perform other styles (with the exception of deathcore bands, which fuse metalcore with death metal and are listed separately).

Bestial Warlust: The band was first formed under the name "Corpse Molestation" and at the time played Black Death Metal with five demos and one demo compilation under the name.  Their lyrical themes involved death, war and blasphemy.  The band also used pseudonyms instead of actual names to hide their identity.  They were one of the pioneers of Australian black metal and extreme metal, recording two black/death metal albums in the mid-nineties before breaking up.  Their style was raw and furious, taking off from the old-school black metal style found in such bands as Bathory, Sarcófago, Beherit, and Blasphemy.  Many members of Bestial Warlust went on to form Deströyer 666 and participate in other Australian extreme metal acts.

Blackgaze: Blackgaze is a fusion genre combining elements of black metal and shoegazing.  The word is a blend of the names of the two genres, described by "The Guardian" as "the buzz term for a new school of bands taking black metal out of the shadows and melding its blast beats, dungeon wailing and razorwire guitars with the more reflective melodies of post-rock, shoegaze and post-hardcore."  According to "Exclaim! ", blackgaze "marries the harsh, alien instrumentation of black metal with the mellower, dreamy soundscapes of shoegaze."  Influenced by atmospheric black metal bands like Ulver and Summoning, the genre was pioneered by French musician Neige around 2005 through the projects Alcest and Amesoeurs and has risen to prominence with the success of American group Deafheaven.  "The Guardian" named Deafheaven "blackgaze's de facto poster boys, the most likely to open up black metal to an even wider audience", and "Exclaim!"  described their second album "Sunbather" – the most critically acclaimed album of 2013 on Metacritic – as seminal to blackgaze.

Extreme metal: Extreme metal is a loosely defined umbrella term for a number of related heavy metal music subgenres that have developed since the early 1980s.  It has been defined as a "cluster of metal subgenres characterized by sonic, verbal and visual transgression".  The term usually refers to a more abrasive, harsher, underground, non-commercialized style or sound associated with the speed metal, thrash metal, death metal, black metal and doom metal genres.  With the exception of doom metal, all of these genres are characterized by fast tempos, attesting to their roots in hardcore punk, which has also fused with extreme metal in the forms of crossover thrash, crust punk, grindcore, sludge metal and metalcore.  Though many extreme sub-styles are not very well known to mainstream music fans, extreme metal has influenced an array of musical performers inside and outside heavy metal.

Slice The Cake: Slice The Cake was an international Progressive Deathcore group spanning from Australia, England, and Sweden.  Formed in 2009, the trio consisted of vocalist Gareth Mason, instrumentalist Jonas Johansson, and composer Jack "Magero" Richardson.  Although the band members are all from different countries, they have played a couple shows with stand-ins.  They released one EP and 3 full length albums before they disbanded.  Their albums have been released to critical acclaim. <br>
