When: January 30, 2012

What Happened: Chief Keef hooks up with fellow Chicagoan King Louie, then the city's dominant street rapper, on a track called “Winning.” The track finds Keef and L at their most triumphant; Keef's chorus has an effortless confidence, and his triplet flow steals the show. Winning serves as an indication of how suddenly Keef's popularity has risen within Chicago's hip-hop scene.
