Baby Cham's breakout single "Ghetto Story" was seen as so incendiary that Jamaican authorities banned it from the airwaves. Speaking truth atop menacing synths and gunshot snares, Cham snarls through his stories of growing up amid violence, poverty, and crime. But while guns-to-glory arcs in the hip-hop and dancehall genres are usually heavy on the braggadocio, Cham isn't boasting — he's lamenting. So he really couldn't be a more appropriate headliner for this charity concert benefiting Jamaican youth still living in the ghetto. Cham's not above giving shout-outs to his mama, so don't think tonight's show fits awkwardly with your Mother's Day plans, either.
