Yesterday, UGK's debut album Too Hard To Swallow turned 20, and to celebrate how Bun B and Pimp C's music has influenced two generations of MCs, this All-Star Tribute to UGK documentary was put together by Sama'an Ashrawi. The 25 minute doc features interviews with Lupe Fiasco, A$AP Rocky, Yasiin Bey, Talib Kweli, Big Boi, 9th Wonder, Killer Mike, Brother Ali, Freddie Gibbs, and more. Watch above.

RIP Pimp C.
