On this set of duets, married R&B duo Lattimore and Moore take on a batch of quiet-storm staples (Ashford and Simpson’s ”Is It Still Good to Ya?,” Billy Preston and Syreeta’s ”Born Again”), along with a few slinky originals. The results are exqui-sitely competent and utterly boring. Both singers have fine voices, especially the Minnie Riperton-like Moore. But their pairings consistently lack heat and seem to be more about politeness than passion.
