Sri Lankan/British iconoclast MAYA "MIA" ARULPRAGASAM makes music that frequently has a sociopolitical message. Her tracks borrow heavily from international forms such as baile funk and booty bass, while her lyrics address everything from boys to feminism and imperialism. Add sing-songy vocals that flit between pop-rap and dancehall styles and you have a world-pop innovator who wins wide critical and commercial acclaim. MIA's tour for her new album, Kala, stops in Atlanta Wed., OCT. 31. Chicago hipsters the Cool Kids open. $22. 9 p.m. Center Stage Atlanta, 1374 W. Peachtree St. 404-885-1365. www.centerstage-atlanta.com.
