Formed in 1976 as the African Disciples, Jamaican vocal trio Culture made an immediate impact on the world outside its island home. The group’s 1977 Joe Gibbs-produced debut, “Two Sevens Clash,” was an instant classic, inspiring the British punk movement of the era with its trio harmonies and militant Rastafarian message. The original group disbanded in 1981, but lead singer Joseph Hill kept performing as Culture until his death in 2006. Since then, his son Kenyatta Hill has carried on the family tradition and the current version of the group is widely recognized as one of the world’s leading traditional reggae acts. Culture comes to Richmond on Friday, Feb. 21, at the Canal Club. And be sure to get there in time to hear local openers Mighty Joshua and the Zion #5. Doors open at 8 p.m. Admission is $12 in advance and $15 at the door. thecanalclub.com.
