Four Malian pop singers star in Mali Blues, a documentary about how the country's biggest acts perform in opposition to Islamic fundamentalists who want to ban secular music and dance in Mali. Directed by Lutz Gregor, the film shows at 7 tonight at the Cleveland Museum of Art, where it also screens at 1:30 p.m. on Sunday. Tickets are $10, or $7 for CMA members. (Niesel)
