David Darnell Brown, better known by his stage name Young Buck, is an American rapper. He signed with Birdman's Cash Money Records in 1997, formed the hip hop collective UTP with Juvenile and Soulja Slim in 2000, and joined 50 Cent's group, G-Unit by 2003. He signed with the latter's parent label, G-Unit Records, an imprint of Interscope Records to release his debut studio album Straight Outta Cashville and its follow-up Buck the World, both of which peaked at number three on the Billboard 200 and were met with critical praise.
Initially launched in 2005 as "G-Unit South", Brown's record label, Cashville Records, has released his subsequent projects following personal disputes with 50 Cent and his 2010 departure from G-Unit Records. Cashville has also signed hip hop acts including The Outlawz and C-Bo.
