As evidenced by the promotion of Smif-N-Wessun's debut album 'Dah Shinin', they--as well as labelmates Black Moon--might've kicked this freestyle on The Tim Westwood Show between 1993-1995.
Both groups also kicked this freestyle at a time when Duck Down Music was just getting off the ground as they branched out from management company to record label.
I want to say that the formation of The Fab 5 (groups Heltah Skeltah & Originoo Gunn Clappaz) took place around the same time as well (correct me if I'm wrong).
But I know that the Boot Camp Clik could've been formed around this time (again, correct me if I'm wrong).
You can give this audio showcase of lyricism a listen below...
