Zimbabwe has only two global-level Afropop stars. One is, of course, Thomas Mapfumo, and the other is Oliver Mtukudzi, who performs tonight with his band the Black Spirits. Mtukudzi, like Mapfumo, is a master musician, has recorded lots and lots of albums and hits, and represents the great future that the small, landlocked country failed to realize after the War of Independence. Mapfumo’s best tune is “Shumba” (“Lion”) and Mtukudzi’s is “Seiko” (“I’m Just Asking Why”). The beauty of the sadness in that tune has no equal in Zimbabwean culture.
