A splendid introduction to Mali's venerable oral traditions. Since the 13th century, Malian griots have told the story of Sundiata, the lion king, who first wrested his throne from a sorcerer, then united West Africa. It's a thrilling tale of destiny and ambition, played out in a world populated by spirits. Niane's version captures the thrill of a Griot's performance.  (WAF48, $16.00)
