Fantasia can definitely let loose when she wants to, but I think she is very capable of showing restraint and control. Performances like her "Sorry Seems to Be the Hardest Word" for Elton John at the Kennedy Center Honors makes me a believer. Summertime could even show those qualities in her.

Speaking of Summertime, Mahalia did sing some Jazz/Blues every once in a while. If you look up her performance of Summertime/Sometimes I Feel Like A Motherless Child, I think you would like it. :)
