Keith Cozart (born August 15, 1995), better known by his stage name Chief Keef, is an American rapper and record producer from Chicago, Illinois. Keef began finding success in his music career while under house arrest, as his music videos were met with local acclaim. His increasing popularity led to a brief bidding war among labels, and ultimately Keef signed a major record deal with Interscope Records; later signing with 1017 Brick Squad. Keef also became the CEO of his own record label, Glory Boyz Entertainment, later developing into Glo Gang. His debut album Finally Rich was released on December 18, 2012.

Since becoming famous, Keef has continued to experience ongoing legal issues. These legal issues, accompanied with Keef's notability within Chicago's drill music genre, have caused Keef to gain a gangster-like image, which has been compared with past gangsta rappers, such as 50 Cent. Despite being dropped from Interscope in late 2014, Keef continued self-releasing mixtapes through his Glo Gang label. Although Keef had originally planned Bang 3 to be released as his second album, a then-track from the album, "Nobody", developed into its own project. Keef released Nobody as a full-length album in December 2014, while continuing to delay the often-pushed back Bang 3.
