Keith Matthew Thornton (born October 7, 1963), known professionally as Kool Keith, is an American rapper and record producer known for his surreal, abstract, and often profane or incomprehensible lyrics. Kool Keith has recorded prolifically both as a solo artist and in group collaborations. Kool Keith is generally considered to be one of hip-hop's most eccentric and unusual personalities.
Kool Keith was a cofounding member of
Ultramagnetic MCs, whose debut ''
Critical Beatdown'' was released in 1988. After two more albums with the group, ''
Funk Your Head Up'' and ''
The Four Horsemen'', Kool Keith released his critically acclaimed solo debut album, ''
Dr. Octagonecologyst'', under the name
Dr. Octagon in 1996. Subsequently he independently released a series of further hip hop albums, including ''
Sex Style'', ''
First Come, First Served'' (as Dr. Dooom), and most recently ''
Keith''.
After releasing only one album on a major label, ''
Black Elvis/Lost in Space'', Kool Keith subsequently returned to independently releasing music, producing further efforts as a solo artist and in collaboration with groups such as
Analog Brothers,
Masters of Illusion,
Thee Undatakerz and
Project Polaroid. Kool Keith has also made guest appearances in collaboration with
Peeping Tom and
Yeah Yeah Yeahs. He was also featured on the short track DDT on
Jurassic 5's album ''
Power in Numbers''.

History
Ultramagnetic MCs (1984–1993)
Thornton began his career with the group
Ultramagnetic MCs under the pseudonym Kool Keith in 1984. Four years later, their release of the album ''
Critical Beatdown'' was critically acclaimed and later became recognized as widely influential for its innovative production, complex rhymes, and chopped sampling. Just after its release, Thornton was reportedly institutionalized in
Bellevue Hospital Center.
However, he later said that the idea that he was institutionalized came from a flippant remark made during an interview, and he never expected the story to become so well known.
Ultramagnetic MCs would release two more albums (1992's ''
Funk Your Head Up'' and 1993's
''The Four Horsemen'') with little commercial success due to
West Coast hip hop

Dr. Octagon debuts (1995–1996)
Thornton released his first notable solo single, "Earth People", in 1995, under the name
Dr. Octagon. This was followed by the release of the

was acclaimed by critics, and the album was released nationally by
DreamWorks Records in 1997, after an initial release on the smaller Bulk Recordings label (as, simply, ''Dr. Octagon'') a year prior. ''Dr. Octagonecologyst'' was considered a departure from old school hip hop to abstract hip hop, with surrealistic, horror, science-fiction, and sexual themes.
DreamWorks also issued an instrumental version of the album, titled ''
Instrumentalyst (Octagon Beats)''.
Further releases (1996–2001)
In 1996, Thornton collaborated with
Tim Dog for the single "The Industry is Wack", performing under the name Ultra
—the album
''Big Time'' soon followed. The following year, Thornton released the sophomore album, ''
Sex Style'', under the name Kool Keith. Thornton described this
dirty rap concept album as "pornocore", filled with sexual metaphors to diss other rappers.
An instrumental version was also released.
This year, a collaborative album with
Godfather Don titled ''
Cenobites'' was released as an LP.
In 1999, he released the album ''
First Come, First Served'' under the name Dr. Dooom, in which the album's main character killed off Dr. Octagon on the album's opening track. The same year, on August 10, 1999, Thornton released ''
Black Elvis/Lost in Space'', under the major record labels
Ruffhouse and
Columbia. It peaked at #10 on the
''Billboard'' Heatseekers chart, #74 on the

chart, and #180 on the
''Billboard'' 200, Despite standing out as Thornton's most commercially successful project to date, he was disappointed with the album's delays and promotional efforts, even though a promotional video was made for the lead single, "Livin' Astro", which aired on a few episodes of the
MTV show ''
Amp'' in early 2000. Its sequel, ''
Black Elvis 2'', was released in 2023.

Second Dr. Octagon album (2002–2004)
In 2002, Thornton began recording ''The Resurrection of Dr. Octagon'' with producer Fanatik J,
signing a contract with
CMH Records to release the album, which was eventually completed without much input from Thornton, due to a falling out over contractual terms.
On October 12, 2004,
Real Talk Entertainment issued the album ''Dr. Octagon Part 2''. The album was discontinued by court order. On June 27, ''
The Return of Dr. Octagon'' was released by
OCD International, an imprint of CMH, advertised as the official follow-up to ''Dr. Octagonecologyst''.
Some critics felt that it was not as good as its predecessor. Thornton stated that he liked the album, but felt that it hurt his reputation as a musician.
In August, Thornton performed under the Dr. Octagon billing, but did not acknowledge the release of the OCD album.

Lyrical and performance style

Thornton's lyrics are often
abstract,
surreal, and filled with
non-sequiturs, extreme violence, exaggerated braggadocio, and profane
shock humor. For example, "Technical Difficulties," from the album ''
Dr. Octagonecologyst'', contains the following lyrics: "Intestines, investments, hide money in your stomach / Who can stop
Pepto-Bismol? Only a Gremlin eatin' in
Larry Parker like Gizmo." In "Extravagant Traveler" from
Matthew, he boasts: "Sautéed fish and shrimp / the

Shawn Kemp," whereas on "Miami Mike" from ''Saks Fifth Avenue'' he proclaims, "I watch you take a shower in my
747 flying over your house / I used to live in the
Twin Towers by myself." Thornton is also known for an explicit style focusing on
sexual themes, which Thornton has referred to as "
pornocore". In a 2007 interview, Thornton claims to have "invented
horrorcore".
Alter egos
Kool Keith is known for his many alter egos. As of 2012, Kool Keith had at least 58 such alter egos: these include well-known aliases such as Dr. Octagon, Dr. Dooom, and Black Elvis, which appeared on albums bearing their names; and the more obscure, such as firearms dealer "Crazy Lou" and "Exotron Geiger Counter One Gamma Plus Sequencer," as he introduced himself in an appearance on
Marley Marl's radio show ''In Control''. Some of Kool Keith's monikers have only existed on album artwork, such as "Mr. Green" and "Elvin Presley."
In reference to his relationship between himself and his various stage personalities, Keith has said, "I don't even feel like I'm a human being anymore".
