The "Time Is Illmatic" trailer for the documentary has been released on YouTube.

Twenty years after the release of Nas' groundbreaking debut album "Illmatic," "Nas: Time is Illmatic" takes us into the heart of his creative process.

"Returning to his childhood home in Queensbridge, Nas shares stories of his upbringing, his influences from the music of his jazz musician father Olu Dara to the burgeoning hip-hop scene in New York City and the obstacles he faced before his major label signing at age 20," according to a description of the movie on the "Time is Illmatic" website.

The documentary features interviews with Nas' "Illmatic" producers, Large Professor, Pete Rock, Q-Tip, L.E.S., and DJ Premier, and musical peers including Pharrell Williams and Alicia Keys.
