"Writer and curator Johan Kugelberg has pulled together the scattered remains of a movement that never had its eye on posterity. The book includes a foreword by legendary DJ and Bronx activist Afrika Bambaataa, a hip hop timeline by best-selling author Jeff Chang, the improvisational flyer artwork of Buddy Esquire, Polaroid photographs buried for decades in basements across the Bronx, and personal contributions from influential figures such as Grandmaster Cas, LA Sunshine, JDL, Mare 139, and Grandwizzard Theodore.
