In my B Side feature on up-and-coming Chicago crew the Village, MC Dikembe Caston (aka Kembe X) compares his community of teenage hip-hop artists to the west-coast scene of the 90s. Today's 12 O'Clock Track is from another big player in Caston's scene, Chance the Rapper; he delivers sharp-tongued rhymes about school-system dogma and getting suspended over a thundering Lex Luger beat on "Fuck You Tahm Bout," a cut from his forthcoming mix tape #10Day.
