Together with partner Pimp C, Bun B formed UGK in the late '80s when their former crew, Four Black Ministers, fell apart. Based in Port Arthur, Texas, UGK signed with Jive, and with 1992's Too Hard to Swallow began a series of Southern gangsta rap albums that were successful sellers. Bun B formed the side project Mddl Fngz in 2000, but his main concern was still UGK. Things came to halt in 2003 when Pimp C was sentenced to eight years in prison on an aggravated gun assault charge. Bun B carried on solo, making numerous appearances on other artists' tracks and then in 2005 releasing both the mixtape Legends and his debut album, the Rap-a-Lot release Trill, a Top Ten hit that was later certified gold. With Pimp C seeing early release in late 2005, Bun B returned to UGK. In 2007, the pair released their chart-topping Underground Kingz, which included the hit single "International Players Anthem (I Choose You)" with OutKast. Tragedy struck in early 2008 when Pimp C died suddenly, leaving Bun B to return to a solo career.
His second solo album, II Trill, arrived months after Pimp C's passing. It became his highest-charting effort to date, rising to number two on the Billboard 200 and topping the R&B/rap/independent charts. His follow-up, 2010's Trill O.G., fared almost as well, peaking at number four. A fourth installment of the Trill series, Trill O.G.: The Epilogue, arrived in 2013 and featured guests Big K.R.I.T., Rick Ross, 2 Chainz, Raekwon, and more, as well as Pimp C on a pair of posthumous tracks, "Cake" and "Don't Play with Me." After a five-year silence, Bun B released 2018's Return of the Trill. Featuring production assistance by Big K.R.I.T. and El-P (whose Run the Jewels appeared on "Myself"), Return also included appearances by T.I., Slim Thug, Yo Gotti, Lil Wayne, Leon Bridges, Gary Clark, Jr., and more. He quickly followed with the collaborative album TrillStatik, which teamed the rapper with producer Statik Selektah. The short set featured guests Method Man, Fat Joe, Smoke DZA, Westside Gunn, Termanology, Talib Kweli, and more. ~ David Jeffries & Neil Z. Yeung, Rovi
