The longest-running hip-hop series, “Rap City,” is getting its own documentary.

The three-part series will air on Tuesday, Oct. 10, roughly three months after the project was initially announced amid hip-hop’s 50th anniversary.

The doc, titled “Welcome To Rap City,“ is being presented by BET and Mass Appeal. It will feature several of the genre’s contributors — including rappers Eve, Ludacris, Jim Jones, T.I. and television executives Debra Lee and Stephen Hill.

Show creator Alvin Jones initially launched “Rap City” on August 11, 1989, as a response to “Yo! MTV Raps.”

The preview trailer opens up with Busta Rhymes reflecting on the show’s legacy during the taping of its finale in 2008. The clip later jumps to T.I., with the rapper sharing, “I ain’t even gon’ front, ‘Rap City’ was like the primary platform for everybody.”

The Atlanta native added, “No matter how big you may see these people right now […] ‘Rap City‘ gave us a launchpad and a countdown to shoot us off into the stratosphere.”
