Oliver Mtukudzi. They use his nickname to describe his easygoing, sparkling folk songs: Tuku music. But don't let the joyous sounds of Zimbabwean singer-guitarist Mtukudzi fool you: the subject matter - sung in his native Shona language - is often dead serious. And as if great recordings weren't enough, the man has been known to deliver a high-energy live show with his group, the Black Spirits. Be at the Kola Note, 5240 Park Ave. on Thursday night at 9 to find out the truth for yourself. Tickets cost $26.50. Phone 514-790-1245 or go to www.admission.com.
