I-Octane is one of those reliable artists whose ship is so steady, he’s sometimes taken for granted. Not at Sumfest, where he was called upon to close Dancehall Night in 2014. The decision was a controversial one, as some including Mr. Vegas called into question Octane’s viability as a headlining act for Jamaica’s biggest stageshow. But Octane afforded himself nicely on the Dancehall Night stage, and he’s been brought back every year since.
