Boogie Down Productions was a hip hop group that was originally composed of KRS-One, D-Nice, and DJ Scott La Rock. DJ Scott La Rock was murdered on August 27, 1987, months after the release of BDP’s debut album, Criminal Minded. The name of the group, Boogie Down, derives from a nickname for the South Bronx section of The Bronx, one of the five boroughs of New York City

The origins of hip-hop are believed to be from the Bronx, a rival hip-hop collective known as the Juice Crew’s lyrics were misunderstood to contain a claim in the song “The Bridge” that hip hop was directly a result of artists originating from Queensbridge. Boogie Down and KRS retorted angrily with songs such as “The Bridge is Over” and “South Bronx,” which started one of the first notable hip hop wars as MC Shan, Marley Marl, Roxanne Shanté and Blaq Poet all released songs featuring verses personally attacking KRS and Scott La Rock.
