Keith Matthew Thornton, better known as Kool Keith, is an American hip hop artist and record producer.

An original member of New York new school pioneers the Ultramagnetic MCs, Kool Keith is best known as a somewhat controversial solo rapper. Keith's signature style of stream-of-consciousness lyrical flow, and his ability to drop complex freestyle vocals with apparent ease, earns him a perennial nod from the underground hip-hop community. Bizarre, disjointed, even delusional or disassociated themes, concepts, and references tend to season the average Kool Keith track or album. Nearly all of his albums incorporate a satirical dislike for more commercialized strains of hip-hop, which he finds to be devoid of any heart. Similarly, nearly all of his works lambast major labels and overhyped MCs.
