On the 15th anniversary of his tragic passing, UGK partner-in-rhyme Bun B paid tribute to his lifelong friend, Pimp C. Bun said that he still feels the loss daily, he's just found better ways to deal with it.

“Not a day goes by that I don’t feel the loss," Bun wrote on Instagram. "I just find better ways to cope with it. Missed and loved but appreciated for the time we did have with you. Missed and loved but appreciated for the time we did have with you. Your spirit lives on in your music and your legacy lives on through your kids. The trillest ever born. They’ll never be another. Love you bro. And it’s still UGK For Life!"

Veteran producer and fellow Houstonian, Cory Mo, also paid tribute to his friend and mentor, who gave him his official start in the business.

"Wow 15 years & we still screaming yo name my nig!" Cory wrote. "It’s UGK 4 Life and a fight go wit dat!! Loooong Live my big brother Pimp C aka Sweet James Jones, aka JR Ewing, aka Percy Mac Millions, aka Jack Tripper, aka The King Of The Sooouf!"

Pimp's influence on southern Hip-Hop is still felt – including through his signature rhyme style, raw honesty, and his organ-heavy, blues-based production which is featured throughout UGK's string of classics, from their 1992 debut, Too Hard to Swallow, and Super Tight, to Ridin' Dirty, Dirty Money, and 2007's Underground Kingz. The latter birthed the instant classic "Int’l Players Anthem (I Choose You)” with Outkast, which helped push the album to debut at No. 1 on the Billboard 200.

Earlier this year, Bun admitted that after Pimp C passed away, he had trouble performing UGK songs.

“Initially, when he passed away, I didn’t want to do day-one songs that would resonate in that way," he told HipHopDX shared. "I come from a community of people where grieving publicly was frowned upon. And so, so many people hold in so much pain. And what happens is that pain comes out at the worst time against the best people and it just puts people in a terrible place."

Pimp C, born Chad Butler, was found dead on December 4, 2007, in a Los Angeles hotel. He was 33.
