Some further information.... those of you who, like me, were avid readers of The Source back in the 90s will remember just how much of an honor it was to be the "Unsigned Hype" columnist.... people who had won that privilege and gone on to do big things include Notorious BIG, Eminem, Common, Mobb Deep, Proof, Pitbull, Saigon... and DMX.
And this exact tape is the one that won DMX that honor in '91.
