Springing out of the eclectic old-school rap outfit the Ultramagnetic MCs, "Kool" Keith Thornton has followed the minor hip-hop trend of adopting different pseudonyms to deliver eccentric and often totally obscure albums on a myriad of different labels. Whether he's donning a wig and assuming his "Black Elvis" character, or presenting himself as the space-traveling gynecologist known as "Dr. Octagon," Kool Keith has consistently proven himself to be one of the most intriguing rappers in hip-hop, aligning himself with some of the best DJs and producers in the business only to cut ties with them, furthering his often erratic image. Schizophrenic, hard to track down, and even rumored to once be a former patient of New York's Bellevue psychiatric ward, Keith is in a totally different league from the Nelly's and Ludacris' of the world. He once told the Boston Herald, "I can rap on any kind of beats, and I can rap on those beats better than those cats. It's like basketball."
