Marc Broussard's early albums established him as the heir to Texas white-soul icon Delbert McClinton. But Keep Coming Back shows the 26-year-old Louisiana singer coming into his own. His coarse baritone fires up the Seventies-style funk of "Power's in the People," the disco-fied anthem "Man for Life" and the warm, strings-drenched piano ballad "Evil Things." He lapses into pedestrian pop-soul-disco on the ponderous "Another Night Alone," but he makes up for it on "When It's Good," a brawny country-soul duet in which he plays Delaney to LeAnn Rimes' sassy Bonnie. With smart collaborations like this, Broussard's soul-music journey has kicked into a comfortable cruise.
