War on Wax tracks the history of rivalries from the beginning of hip hop with early battles like KRS-One vs. MC Shan and Kool Moe Dee vs. LL Cool J, up until the legendary East Coast/ West Coast rivalry which culminated with the deaths of Notorious B.I.G. and Tupac Shakur. The documentary explores how the media has capitalized on feuds and manipulated them, and how the evolution of rivalries grew from dissing a rival on a track to more dangerous and physically threatening hatred. The film features in-depth interviews with various hip hop artists and industry insiders commenting on rivalries they were involved in and their thoughts on the multitude of feuds throughout hip-hop history.
