Kurtis Blow, Nas, Rev Run, and Roxanne Shanté sat down for an a16z Paid in Full fireside chat to trace hip-hop from its actual origin point: 1970s Harlem, a broke and broken New York City where, in Blow's words, 'we had nothing.' Blow was there before the genre had a name, before block parties became a business, when disco, DJing, and urban crisis were the raw inputs.

What makes this worth watching in full is not the nostalgia. It is the specific cultural mechanics. Blow walks Nas through how disco fed directly into hip-hop's DNA, how the block party format was the first distribution network, and how a city in fiscal collapse accidentally created the conditions for a global art form. Rev Run adds a generational layer, connecting Blow's foundational work to what Run-DMC built on top of it.

Roxanne Shanté's presence matters here too. The conversation covers not just the music but the people and decisions that shaped who got credit and who got paid. This is primary source material from four people who were not observers of hip-hop history. They were the mechanism.
