With the Impressionists at the Kimbell and all the King Tut hooplah taking over the Dallas Museum of Art, you might not have noticed that the other blockbuster exhibition in the area — and one that’s just a leettle more contemporary and risk-taking than the other two — closes this weekend. It’s your last chance to see Kara Walker: My Complement, My Enemy, My Oppressor, My Love at the Modern Art Museum of Fort  Worth. Here Walker is, talking about some of her 2004 installation, Fibbergibbet and Mumbo Jumbo, work she did while an artist-in-residence at the Fabric Workshop and Museum in Philadelphia. It’s some of her most consciously “theatrical” art about slavery and the pop culture imagery of African-Americans – using, as it does, stage sets, shadow puppets, projections, paintings and videos of her own performances.
