Before there was radio play and platinum albums, there were city cyphers; emcees gathered to rhyme purely for sake of rhyming. We created DJBooth's new City Cypher series in that spirit. In any city we can find dope rappers and a street corner, we'll be bringing together emcees to showcase their skills. For the first episode, we had to keep it NYC and set up shop on a Brooklyn rooftop. It's just turntables, a mic and emcees Black Dave, Emilio Rojas, Maffew Ragazino, HD and Kirk Knight going in.
