The U.S. denied M.I.A. a visa to work on Kala, but she showed us by making an album that's an exercise in audio globetrotting, almost as if she was taunting us with all the directions she could go in. Pit stops include Bollywood psychedelia, clucking, chutney-bhangra, vocals from a South Asian Donna Summer, Nigerian MC Afrikan Boy, a teenage Australian Aboriginal hip-hop crew, tribal vocoders, electro-reed mouth organs, an apocalyptic rave, a Yeah Yeah Yeahs song about counterfeiting passports and Timbaland. Feel confused, even assaulted, yet strangely enticed? Ah, then, she's done it again.
