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.
Just Be Free is a demo album released by Warlock Records featuring music recorded by American recording artist Christina Aguilera.
 After finishing her run on "The New Mickey Mouse Club", a then fifteen-year-old Aguilera began recording the album with New Jersey-based producers Roberts Alleca and Michael Brown.
 The pair gave Aguilera the opportunity to use a recording studio and presented her with demo music with the understanding that they could use the material for their own purpose, but also claiming they would not commercially release the recordings.
 Musically, the album consisted of dance style tracks as well as ballads, and saw Aguilera performing in Spanish language songs.
 The record was conceived to showcase Aguilera's vocals in an effort to reach out to record labels, a venture which actually backfired after the recordings were not very well received among critics.
 Six years after the completion of the album and Aguilera had achieved mainstream success, Brown and Allecca released the record and "Just Be Free" has sold over 128,000 copies in the United States.
Open-source record labels are record labels that release music under copyleft licenses, that is, licenses that allow free redistribution and may allow free modification of the tracks.
The English city of Bristol has, since the mid-1970s, had a particularly fertile music culture, resulting in not only a great many influential musicians and bands, but also its own sound, Bristol sound or trip hop.
 Along with the music, a number of local record labels also developed, some receiving national and international attention, others with a smaller audience appeal.
 In the 1970s, there was a DIY culture of record production and the independent record label came to prominence.
 One of the most successful at that time was Virgin Records started in 1972.
 Chiswick Records, Stiff Records, Rough Trade Records and Factory Records followed.
 By the later part of the decade, Virgin had become a part of the music business establishment, and new independent record labels began appearing in virtually every British town and city: Bristol was no exception.
 One of the very first Bristol punk bands, The Cortinas released its first single on Miles Copeland's Step Forward Records in 1977, eventually moving on to CBS before disbanding.
 Copeland also released, in 1977, The Pigs' Youthanasia EP on his newly formed New Bristol Records.
 The explosion in punk/new wave bands forming in the area did not attract interest from the major London-based record labels, so local labels sprung up to release recordings from these groups.
 Amongst the first, and initially more successful, were Heartbeat Records, Fried Egg Records, Recreational Records and Riot City Records (a Heartbeat subsidiary).
 Others with more modest success were Wavelength Records (although its subsidiary Bristol Recorder, did achieve some popularity), Circle Records and Sheep Worrying.
 Some bands set up their own labels: Black Roots (Nubian Records) and Essential Bop (Monopause Records).
 Yet other labels, although not based in Bristol, had a strong representation of bands from the area: Y Records, Rialto Records and Naïve Records.

Total Eclipse Anthology is a compilation album released by Bonnie Tyler in 2002.
 The two disc album consisted of material that Tyler had released on all of her previous record labels up until that point: RCA, CBS, Hansa Records and EastWest.
 With tracks included from her first ten albums, the anthology was fairly comprehensive.
 However, no tracks were included from Tyler's albums "Free Spirit" (1995) and "All in One Voice" (1998).

El Saturn Records is an American record label founded in 1957 by Alton Abraham.

 Notable albums released by the label include works by Sun Ra.
Ritmoteca.com was an online music store and early pioneer in the online downloadable music space.
 Founded in Miami, Florida in 1998 during the Dot-com bubble by Ivan J. Parron, and Ricardo Decubas, the company was the leading Latin music download website and an early predecessor to Apple Inc.'s now highly successful iTunes business model of selling digital music downloads over the Internet.
 Mr. Parron founded the company after operating the successful web development company Internet Marketing Consultants, which designed Ritmoteca's revolutionary graphical user interface for retailing online music.
 Ritmoteca.com aggregated exclusive digital distribution rights from over one hundred independent Latin music record labels and amassed a library of over 500,000 music tracks and videos, including exclusive digital distribution rights to catalogs of some of the worlds top renowned Latin artists such as Marc Anthony, Tito Puente and Celia Cruz.
 The company was also the first digital Latin music companies to sign digital distribution agreements with the major record labels, signing agreements with Universal Music Group, Sony Music Entertainment, Bertelsmann Music Group and Warner Music Group.
 These agreements gave the company digital distribution rights for artists such as U2, Madonna, Britney Spears, Enrique Iglesias and Jay-Z.
 The company grew to as many as 200 employees through investments from institutional and "angel" investors including Bain Capital.
 The company forged key strategic alliances with companies including Microsoft, MSN, AOL, Pressplay and Creative Labs, becoming the go-to source for Latin digital music.
 The company was poised to launch an initial public offering when the Dot-com bubble stock market suddenly crashed on April 14, 2000.
 That event, combined with the emergence of the company Napster on the music scene, enabling people to trade music online for free, made it virtually impossible for the company to raise additional venture capital and continue its rapid growth.
 The company evolved into a distributor of digital music rights and eventually closed down in 2005.
