British/Sri Lankan beauty M.I.A. announced that she?s ready to release her sophomore effort, Kala, on June 25th. The follow-up to her critically acclaimed 2005 album Arular features collaborations with beat-whiz Timbaland and avant-hop-head Diplo. (She?s worked with Timbaland before; there?s a bonus track on the U.K. version of Shock Value called ?Come Around? to that effect.) M.I.A., whose work thus far has been both sexually charged and a lightning rod for political controversy, has been hard at work on making challenging music. It?s not always the most danceable, but we love the title of her first single (which you can hear at her MySpace page): ?Bird Flu.? Anyone care to guess at the titles of other tracks on the album? We?re hoping for ?Project Red? and ?Niger Yellowcake.?
