Chaka sings like Ali boxed: so smooth and agile it’s almost confounding how hard she can hit, too. It took some all-star ultra-opulent instrumentation and composition just to keep up with her voice, and whether the mode was funk, disco, or R&B balladry, she took songs by Ashford & Simpson (“I’m Every Woman”), George Benson (“We Got the Love”), and Stevie Wonder (“I Was Made to Love Him”) into the stratosphere.
