Femi Kuti and the Positive Force (Sunday) The vivacious Mr. Kuti, the eldest son of Fela Kuti, laces his Afrobeat ancestry with fluid funk and topical hip-hop. He also collaborates regularly with some of the most incisive rappers around, including Common and Yasiin Bey. Mr. Kuti’s slow-burning “Tension Grip Africa,” from his 2008 record, “Day by Day” (Downtown), is an especially remarkable peak in his recent catalog. He performs as part of the SummerStage Festival, with Sinkane. At 3 p.m., Central Park SummerStage, Rumsey Playfield, midpark at 70th Street, (212) 360-2777, summerstage.org; free. (Anderson)
