Few voices in hiphop, or all of pop music, are as distinct and divisive as Dizzee Rascal's. Rising out of the critically praised (but commercially stillborn) East London grime scene, Rascal raps with a rubbery, harsh, heavily accented bark that evokes grim council estates, CCTV paranoia, and druggy urban smog. But Rascal's England is also one of world-conquering ambition, as announced on his monumental, upwardly mobile anthem "Fix Up, Look Sharp." With Brooklyn-born MC and producer El-P. (Neumo's, 925 E Pike St, 709-9467. 8 pm, $17 adv, all ages.)

Earlier this year, Seattle filmmaker Sandy Cioffi and her crew were traveling in Nigeria in search of closing footage for Sweet Crude, her documentary about life in the dirt-poor-but-oil-rich Niger Delta. On April 12, they were apprehended by the Nigerian military and held for seven harrowing days. Tonight Cioffi joins an international panel of journalists and human-rights advocates to parse "the deeper story and larger issues" behind her detainment and the growing risks of international journalism.
