So instead, the man is here to “funk it up.” Celebrating his freshly released album, Where Does This Door Go, the Detroit-bred soul man covered “Royals” for VEVO’s “Unexpected Covers” series, enlisting his full band to give the electronipop delight an afterhours jazz rebirth. The groove is undeniable and the four-part harmonies are divine. Bear witness above, and read our interview with Lorde to find out who’s been inspiring her along the way.
