Once detained by the Haitian police to prevent their performing anti-military-rule material at Carnival time, the members of Boukan Ginen are now free to sing their Creole-tongued protest lyrics in their homeland. On its debut disc, Jou a Rive (The Day Will Come), the 10-piece outfit accompanies its political sentiments with traditional rara percussion as well as slick-sounding keyboards and drum machines. While the latter occasionally bogs things down, the band’s best material marries the group’s soaring vocals with insistent rhythmic patterns. At 10 p.m. at Kilimanjaro, 1724 California St. NW. $15. (202) 328-3838. (Steve Kiviat)
