American soul singers, stand down. Nigeria's got a lock on it, in the form of one Nneka Egbuna, the half-Nigerian, half-German singer who's got Erykah Badu on the brain and Macy Gray in the pipes. Rarely has a singer sounded so passionate and catchy at the same time, with top-shelf production ricocheting between R&B, hip-hop and reggae while her lyrics tackle, you know, the usual: love, exploitation in the Nigerian delta, feelings, the horrors of unbridled capitalism. It's a heady mix, and one that threatens to make R&B socially relevant again. Think Curtis Mayfield rather than R. Kelly.
