Rosemary Nalden has stopped her ensemble of 20 young South African musicians in the midst of a Scott Joplin tune. They're in rehearsal at the Santa Monica Presbyterian Church. "It's not in tune still," she says to them. "Wake up, all of you--you're so dozy today." The group is jet-lagged--just off the plane from Soweto, the South African township known more for its 1976 anti-apartheid student uprising than for high culture.
