Keith Thornton co-founded the Bronx group Ultramagnetic MCs in 1984 and, on 1988's Critical Beatdown, helped invent a denser, funnier, more chopped-up style of rhyming and sampling than the genre's still-forming rulebook allowed. He has spent the decades since multiplying into aliases — most famously Dr. Octagon, the alien gynecologist-surgeon of 1996's Dr. Octagonecologyst — stacking sci-fi filth, horror-movie dread and stream-of-consciousness non sequiturs into a style that made him underground rap's patron saint of the deliberately unhinged.
Keith has said watching his friend Kay Gee make the Cold Crush Brothers was the spark that got him rapping at all — seeing a neighborhood kid join one of the Bronx's most polished crews made the whole thing feel reachable.
listen forCold Crush's tightly drilled call-and-response routines on ‘Punk Rock Rap’ are a world away from Kool Keith's own free-associating chaos, but the same crew-built showmanship resurfaces, warped, in Dr. Octagon's ensemble-cast weirdness on ‘Halfsharkalligatorhalfman.’
Keith has cited Treacherous Three as the group that showed him rap could be a lyrical weapon rather than a chant — “it was the first time rap was really getting lyrical” — a lesson he took further than almost any other MC.
listen forThe tongue-twisting double-time cadence Treacherous Three debuted on ‘New Rap Language’ is the direct ancestor of the breathless, syllable-stuffed verses Kool Keith unloads on ‘3000.’
Keith has described watching Grandmaster Flash and Melle Mel walk Fordham Road dressed like nobody else — “they had presence” — the larger-than-life star quality he later chased through a rotating cast of alter egos.
listen forThe showmanship and vocal command of the Furious Five's ‘The Message’ gets refracted into pure theater on Dr. Octagon's ‘No Awareness,’ where Keith performs a whole cast of unhinged characters instead of just one persona.
