As the name implies, St. Lucia has an exotic bio. Jean-Philip Grobler is from South Africa and toured the world as a member of the Drakensberg Boys Choir School before studying music for three years in England. (These days, he calls Brooklyn home.) Grobler hasn’t totally left his choir-boy days behind, as his beautiful voice melts easily around the immaculately layered music of the new self-titled EP, out now on previously singles-only label Neon Gold. The band doesn’t need hyper-catchy choruses to conduct Grobler’s epic orchestral maneuvers in the dark, but St. Lucia pulls out all of the stops during “Closer Than This,” which ends the EP with an euphoric exclamation point.
