About Chief Keef Kicking his career off at the age of 16 with the street single 'I Don't Like,' rapper Chief Keef was a hit on Chicago's high school circuit before mixtapes and viral videos led to a contract with Interscope. Born Keith Cozart in Chicago, Keef first hit with 2011's 'Bang,' a slow-rolling, simple cut that was an instant hit with the youth of his hometown's South Side. The mixtapes The Glory Road and Bang were both released that year by Keef's label, Glory Boyz, but at the end of 2011, the rapper was arrested for unlawful use of a weapon, having pointed a gun at a police officer. In early 2012, Keef was finishing his sentence of house arrest at his grandmother's home as his track 'I Don't Like' was topping a million views on video-sharing sites. It caught the attention of Kanye West, who completed a remix of the track with Big Sean, Pusha T, and Jadakiss all added to the mix. The single landed on Finally Rich, his debut album released late in 2012 by Interscope.
