This album opens with a sly little JB guitar sig, a quick turntable scratch and KRS-One declaring, "Class is in session." And though KRS would become hip-hop's self-anointed teacher, the lesson here is murky and violent. KRS threatens Marley Marl's Juice Crew on "South Bronx," "bucks down a crack dealer named Peter" on "9 MM Goes Bang" and concludes that "the girlies are free 'cuz the crack cost money" on "P is Free Remix." Shortly after the release of this album, Scott La Rock was shot down in the Bronx, a tragedy that would forever transform both KRS and hip-hop. This reissue features a bonus disk of remixes, B-sides and outtakes.
