Keys’ retro-soaked neo-soul—with its piano-heavy arrangements and classic R&B styling—is perfectly suited to MTV’s Unplugged format. Stripped of any slick production flourishes, the New York native’s vocal chops and soulful songwriting are on full, unfettered display. Vintage reworkings of chart-smashing pop ballads like “Fallin'” and her legendary collab with Adam Levine to cover the Stones’ “Wild Horses” sit seamlessly alongside then-new single “Unbreakable,” a finger-snapping, sizzling funk groove.
