Maxwell and Jill Scott
Sure, these well-known soul stars are popular and powerful enough on their own. But together, they're a sweetly unstoppable sonic force, as lucky fans will find with they co-headline a national tour in May. The Grammy-winning Scott is a triple threat: She sings with subtle brilliance in her multi-album series "Words and Sounds," acts in films from Tyler Perry and Anthony Minghella, and even formed the education-minded charity Blues Babe Organization. Meanwhile, the Brooklyn-born Maxwell has been dominating award ceremonies and sales charts since arriving in the late '90s. With longevity to spare, both are already lined up next to the legends of yesteryear.
