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.

They 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.

Cameramen and women discuss the craft and art of cinematography and of the “DP” (the director of photography), illustrating their points with clips from 100 films, from Birth of a Nation to Do the Right Thing. Themes: the DP tells people where to look; changes in movies (the arrival of sound, color, and wide screens) required creative responses from DPs; and, these artisans constantly invent new equipment and try new things, with wonderful results. The narration takes us through the identifiable studio styles of the 30s, the emergence of noir, the New York look, and the impact of Europeans. Citizen Kane, The Conformist, and Gordon Willis get special attention.
