To celebrate what would have been Pimp C’s 45th birthday on December 29, Bun B dropped an emotive live rendition of his recent tribute to his close friend and partner in UGK. It has been 11 years since highly influential MC/producer Chad Butler passed away in West Hollywood due to complications codeine syrup consumption related to his sleep apnea.

Pimp had started Underground Kingz with Bun in their hometown of Port Arthur, Texas when the two were just teens in the last 1980s. The duo dropped their debut, Too Hard To Swallow, with Jive Records in 1992, and they released their fifth studio album, Underground Kingz, exactly four months before Butler’s untimely passing on December 7, 2007. With some help from affiliates OutKast and Three 6 Mafia, that Jive LP went to #1 for a group long known for its Underground status.

After a five year hiatus from solo albums, Bun made a comeback in 2018 with his well-received fifth album Return Of The Trill. The offering includes a heartfelt dedication to his late great compatriot, “Gone Away,” that features Gary Clark Jr. and Leon Bridges. A live version of the sorrowful yet celebratory song performed by Bun and Clark Jr. has now been made public. Bridges strums his electric guitar while Bun raps his verse without a waver. Viewers can see the pain in the Houston legend’s face as he joins in on the chorus.

Pimp C is a guest on Bun’s latest album, which also features Run The Jewels, Big K.R.I.T., 8Ball & MJG, as well as others.
