(AllHipHop News) Fans of veteran Hip-Hop group Underground Kingz will get an inside look at the group in a new documentary being released next month titled Kings of the Underground: The Dramatic Journey of UGK. The DVD chronicles UGK's early beginnings in Port Arthur, Texas, to their rise to the top of the charts and the personal struggles the group faced during their 20-year-career, including Pimp C.'s incarceration and death in December of 2007. The Dramatic Journey of UGK was directed by Thomas Gibson, who interviewed artists like Rick Ross, Lil Wayne, Big Boi, Slim Thug, T.I., Three 6 Mafia and numerous others for the DVD. "That's all we had coming up, just that music, the whole UGK vibe. They was stuntin in a different language, I loved how their pimp down," Cash Money's CEO Bryan "Baby" Williams said of the group's influence on the south and Hip-Hop music in general. To this day, the group and surviving member Bun B. continue to release material. Bun. B's album Trill OG was released yesterday (August 3rd) to critical acclaim. Today (August 4th), The Source Magazine announced that Trill OG had obtained its coveted 5 Mic rating in the fall Back to School issue, which is slated to hit stands on August 17th.
