In July, Jamaica’s most influential living artist walked out of a Kingston prison after 13 years, drove straight to his mother’s house for a tearful reunion over steamed fish and okra — and dove immediately into preparations for Freedom Street: his first performance since his release, and the biggest concert the country would see in nearly 50 years.

Locked up for the murder of Clive “Lizard” Williams, Vybz Kartel went away as a 35-year-old man at the height of his career with seven children, two of whom would make their own musical debuts in 2014. But even behind bars, he never stopped making music — managing to secretly record and release five projects that would reach the top 10 of Billboard’s Reggae Albums chart.

“Being in prison, you can’t feel sorry for yourself. I didn’t have time to do that. I had kids to feed. I had family to take care of. I had health issues, too,” Kartel tells Billboard in a private room at Downsound Records, the live-entertainment producer behind Freedom Street, in Kingston. “There was no time to be weak. You just fight the case and do the right thing.”

Now, just days before Freedom Street — his New Year’s Eve show that will draw over 35,000 people to Kingston’s National Stadium — Kartel tells me he’s been holding daily three-hour rehearsals to ensure a “Taylor Swift- or Madonna-style” show while he records a new album at several studios, including one his children built for him while he was away. As I follow the Teacha around Kingston over the course of a sunny December day, fans of all ages stop him to profess their love and grovel for selfies — and if they aren’t trying to get his attention, they keep their eyes glued to him and hum whatever song of his comes to their minds.
