“Kool” Keith Thornton is a rapper from the Bronx, New York, rapping under the names Dr. Octagon, Dr. Dooom, Keith Korg, Mr. Nogatco and most notably, Kool Keith.

Keith is known for his abstract, sexual, and oftentimes shocking rhyme style, which he has referred to in the past as both “pornocore” and “horrorcore,” the latter he claims to have invented. He is both a solo artist and a member of the groups Ultramagnetic MCs, The Analog Brothers (with Ice-T, Marc Live, Black Silver and Pimp Rex), Ultra (with Tim Dog), Masters of Illusion (with Motion Man and producer Kutmasta Kurt), Thee Undatakerz, KHM/The Clayborne Family (with Marc Live and H-Bomb), and Project Polaroid (with producer TomC3).

Keith got his start as part of the Ultramagnetic MCs, a group he formed in 1984 with Ced Gee, TR Love, and Moe Love. After the release of their first album Critical Beatdown in 1988, Keith released two more albums with the group before embarking on a solo career. They’d later reunite for a fourth album in 2010.

Keith’s solo debut album, Dr. Octagonecologyst, was released in 1996 with Keith billed as Dr. Octagon. He’d go on to release over two dozen projects as both a solo artist and as part of a group, with 1999’s Black Elvis/Lost in Space standing as his most commercially successful project to date.
