This ballsy underground hit by Mobile, Alabama rapper Mr. Bigg is Southern hip-hop’s ultimate innocent-until-proven-guilty pleasure. A full-on courtroom confession, “Trial Time” details his decade-plus career in the drug game with shameless pride: “I was only 17, had the neighborhood hooked / Had 'em stealing out they crib ’cause my crack taste like ribs.” But despite the scale of his crimes, Mr. Bigg fearlessly taunts the judge, the D.A., and the “12 white folks” in the jury box with the song’s addictive refrain, “Take that shit to trial, bitch!” Can Scorsese make a movie about this guy already?
