Born on March 15, 1981, in Nashville, Tennessee, Young Buck gained prominence in the early 2000s, becoming a notable figure in the music industry due to his association with several high-profile record labels and artists, particularly during his time with 50 Cent and G-Unit.

Young Buck's musical journey began in the late 1990s when he affiliated with Birdman and his Cash Money Records in 1997. He formed the hip-hop collective UTP (Under the Influence of the Southern Plug) alongside fellow artists Juvenile and Soulja Slim in 2000. However, it was his collaboration with 50 Cent that marked a pivotal point in his career. By 2003, Buck had signed with 50 Cent's G-Unit Records, an imprint of Interscope Records, which allowed him to launch his solo career.

In 2004, Young Buck released his debut studio album, Straight Outta Cashville, which received critical acclaim and peaked at number three on the Billboard 200.

Despite his success, Young Buck's career has been marred by personal and professional challenges. In 2010, he left G-Unit Records following disputes with 50 Cent, prompting him to establish his own label, Cashville Records, initially launched in 2005 as "G-Unit South." Under Cashville Records, Buck has continued to release music and expand his artistic endeavors, signing other hip-hop acts including The Outlawz and C-Bo.
