The main event at fight night in Kingston, a popular boxing showcase, was hours away, but the crowd at the National Stadium's indoor arena, from the young and hip to the elderly, was already pumped.

A musical and social roots movement called "Reggae Revival" is on the rise in Jamaica, where the raunchier dancehall genre has been king for the last two decades. The revival evokes music from reggae's golden era of the 1970s, dominated by the late, laid-back legend, Bob Marley, who put reggae on the global map with his catchy tunes and spiritual and socially conscious lyrics.
