Nas Discovers The Man Who Made His Ancestors Slaves In This Astounding New Clip

Nasty will be featured in the new season of 'Finding Your Roots' on PBS.

In the new season of the PBS show "Finding Your Roots," Nas will come face-to-face with how his family was affected by the United States' dark history of slavery.

The show, which takes an individual's DNA sample and uses it to trace their ancestry, will feature Nasty as the first rapper when its second season kicks off in the Fall.

But as enriching of an experience as it may be to learn about familial history, it still seemed to leave Nas with a bit of uneasiness. In the trailer for the upcoming season, Esco stares contemplatively for the first time at a picture of the man who enslaved his ancestors, clearly trying to process the gravity of what those ancestors experienced. And that's not all.

"First I was enraged when I looked at the bill of sale," he said during a recent panel discussion, according to Billboard, in reference to an 1859 documentation of one of his ancestor's being sold. "I was like, that guy that owned property owes me some cash. My people made him really wealthy, so maybe I should find his family and talk."

Other guests on the series, which is hosted by Harvard professor Henry Louis Gates Jr., will include Ben Affleck, Derek Jeter, Jessica Alba and Stephen King.

The burst of new knowledge seemed to leave the Queens native eager for additional discoveries. "Now I'm on a mission to find out more," he said.

The new season of "Finding Your Roots" will air on September 23.
