Keith Matthew Thornton (born 7 October 1966), better known by his stage name Kool Keith, is an American rapper from The Bronx, New York. He is known for his surreal, abstract and often profane or nonsensical lyrics. Kool Keith has recorded prolifically both as a solo artist and in group collaborations.
Kool Keith began his career as a cofounding member of Ultramagnetic MC's, 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. He subsequently released a series of further independent hip hop albums, including Sex Styles and First Come, First Served.
After releasing one album on a major label (Black Elvis/Lost in Space), Kool Keith returned to independently releasing music, producing further albums as a solo artist and in collaboration with groups such as Analog Brothers, Masters of Illusion and Thee Undatakerz.
