This winter's bitter spat between Nicki Minaj and Remy Ma was merely the latest chapter in a decades-long hip hop battle for supremacy between the Queens and Bronx. The interborough rivalry dates back as early as 1987, when the South Bronx's Boogie Down Productions squared up (lyrically) against Queens' Juice Crew.

BDP formed in the mid-1980s after a then-homeless KRS-One attempted to steal subway tokens from the 166th Street Franklin Armory Men’s Shelter, where Scott La Rock worked. They would soon join force—KRS on the mic, Scott on production—and forge a sharp, politically charged style that would soon be heard New York and the country over.
