"Miss Red (Sharon Stern) is an Israeli dancehall MC with an effortlessly sharp, excited flow, frequently punctuating her rapid-fire rhymes with squeaks, and she's just as adept at switching into a calmer, more detached mode. Ever since she spontaneously took the stage during a 2011 gig by the Bug (Kevin Martin), the two have been frequent collaborators, both on-stage and in the studio ... Both Martin and Stern are fully aware of how far removed from the Jamaican dancehall scene they are, and while they're faithful to some aspects of the genre, they don't sound like they're aping it, and they're certainly coming at it from their own perspectives. K.O. is their most successful collaboration so far, and a flat-out thriller above all else".
