Even beyond their hits, Rufus & Chaka Khan flex the pop chops that landed them on the R&B charts throughout the ‘70s and '80s. "Dance Wit Me" is the kind of rubbery funk that first earned the Chicago group attention, while latter-day solo output from Chaka Khan—such as "Angel" and the Hendrix cover "Castles Made of Sand"—is true grown-folks soul. The funky disco of “Stuff Like That” is the perfect canvas for Khan’s husky cameo.
