Fela! boasts hit songs, thrilling dances and a riveting story. But this Broadway success, which runs through Sunday at the Adrienne Arsht Center, is also radically different from other musicals. The show, which opened Tuesday evening, brings us inside the seething, incandescent and precarious life of the Nigerian musical and political revolutionary Fela Anikulapo Kuti. That it succeeds in captivating American audiences with a world that would seem to be utterly foreign and disturbing to them is part of its achievement. Fela! does not lecture. But like the life of its subject, the show is celebratory and tragic in equal measure.
