Badu and her large turban appeared out of nowhere in early 1997, on a murmuring, romantic album that trod the median between old-school soul and contemporary electronic R&B. Badu's songs, especially the hit "On & On" and the catchy "Certainly," recall Sade in their polished, subtle sexiness. Badu almost never raises her voice--save the occasional "ooh-wee!" exultation--but she skillfully uses repetition and chanting to empower her words. Later portraying a beautiful swamp queen, she was one of the only good things about the movie Blues Brothers 2000. --Steve Knopper
