Oliver "Tuku" Mtukudzi: The news from Zimbabwe is an unremitting disaster, as one of Africas great hopes has collapsed into hyper-inflation, repression, and political paranoia. The countrys musical offerings remain stellar, however, and though it might take more than Oliver Mtukudzis gentle voice and soul-filled midtempo music to alleviate the countrys suffering, its surely a welcome balm. Tuku, a cult figure in Zimbabwe and one of African music's living legends, has a brand-new album, Tsimba Itsoka. The title means No Foot, No Footprint, which rings like an oblique, proverbial statement about action and responsibility. At Somerville Theatre, Oct. 19. Tickets $28. worldmusic.org, 617-876-4275.
