Femi Kuti carries the torch for his late father, Nigerian Afro-beat pioneer and superstar Fela Kuti, the subject of the exhilarating recent Broadway musical sensation Fela! Femi Kuti and the Positive Force's Afro-beat expands on his father's funky jazz base to incorporate the sounds of new R&B and dance music from all corners of the world -- but it's as tinged with activism, especially against oppressive, corrupt government, as his father's music. Tonight, Saturday, April 23. Doors at 10 p.m. Nightclub 9:30, 815 V St. NW. Tickets are $30. Call 202-265-0930 or visit 930.com.
