Keith Cozart (born August 15, 1995), better known as Chief Keef, is an American rapper and record producer from Chicago, Illinois. During his teenage years and while under house arrest, Keef’s music videos were met with acclaim from local high school students.

His popularity led to a bidding war among labels. Ultimately, Keef signed with Interscope Records and later signed with 1017 Brick Squad. Keef also became the CEO of his own record label, Glory Boyz Entertainment, which later developed into Glo Gang.
