On Good Things, Aloe Blacc styles himself as a 21st-century guardian of a bygone era, using his smoky voice on stylish soul and funk numbers that shimmer with vintage charm. Songs like “I Need a Dollar,” with its rich horns and peppy percussion, and “Hey Brother,” which is fueled by nasty wah-wah guitars, sound like lost cuts from the Stax vaults. He even puts his own stamp on The Velvet Underground’s “Femme Fatale” by reimagining it as a warm R&B number.
