At the very center of the wonderfully rich Bay Area jazz scene stands Kim Nalley, an accomplished vocalist, jazz academic, writer, and businesswoman. Just a few months after earning her Ph.D. from UC Berkeley, the fabulous Ms. Nalley makes a return to the Kuumbwa Jazz Center, bringing her spine-tingling interpretations of Nina Simone, Alberta Hunter, Aretha Franklin and countless others, as well as her original songs heard on such stellar albums as her 2015 release, “Blues People.”
