It's hard to believe that it's been 20 years since Nas dropped Illmatic, on April 19, 1994, so the Queens rapper is celebrating the milestone with a little refresher course on his debut album.

Three days ahead of the LP's anniversary date, on April 16, Nas will kick off the 2014 Tribeca Film Festival with the premiere of his new documentary "Time Is Illmatic." The film, produced by One9, Anthony Saleh and Erik Parker, retraces his influences and journey to create the album, and explores its lasting effect on hip-hop culture, which has already spanned two decades.

Nas will follow the premiere with a live performance of the entire album, making it a pretty special event.

In addition to debuting his documentary at the Tribeca Film Festival, the Queensbridge rapper will also drop Illmatic XX in April, featuring both original and remixed versions of the songs that appeared on his original album.

Still, that's not all. Nas will be rolling out a new, half-hour autobiographical drama series called called "Street Dreams" on Xbox. The series will be set in the 1990s in Queens, New York, and follow the early stages of his career. A premiere date hasn't been announced as yet.
