Keith Cozart, (born 15 August, 1995) better known by his stage name Chief Keef, is an American rapper from Chicago, Illinois. He has signed a major record deal with Interscope Records, and is the CEO of his own record label Glory Boys Entertainment.
The attention he received grew in the short time between the release of several mixtapes and several music videos, including Bang, 3Hunna and I Don't Like.
After two locally successful mixtapes, I Don't Like became a hit in Chicago. It also caught fellow Chicago rapper Kanye West's attention, and West organised a remix of the song, along with rappers Pusha T, Jadakiss and Big Sean.
