“Soul of a Woman” is a final set of genre-perfect old-school soul: brisk rumba-soul in “Sail On,” hand-clapping neo-Motown in “Rumors,” a girl-group slow dance topped with hovering strings in “When I Saw Your Face.”

The band sounds as if it’s playing live in the studio, each instrument in a fixed place — usually drums on the left, organ on the right — with its grooves seasoned by years of playing together, its horn section taking pride in every unanimous note.
