Public Enemy’s Chuck D leads a cast of hip-hop icons and leading African-American and Latino cultural commentators as they chart the factors that led to the birth of the revolutionary art form of hip-hop in 1970s New York, as well as the creation of the seminal hit The Message.nnThey evoke a picture of how, after the turbulence of the 60s and the civil rights struggles, desperate social conditions and the experience of countless dispossessed people of colour living in a city mired in crisis helped give birth to a new art form.
