From Wikipedia:
After Graceland, Simon acted as producer on three records for the group aimed at the American market, Shaka Zulu (1987), Journey of Dreams (1988) and Two Worlds, One Heart (1990). On the latter album, the group recorded with The Winans, Julia Fordham and George Clinton among other then-popular artists. Shaka Zulu was nominated (and won) in the category of Best Traditional Folk Recording in the Grammy Awards 1988.
