John Legend's deep appreciation of soul shines when he works with collaborators who fuel his curiosity and innovation, like La La Land director Damien Chazelle and streetwise violinist Miri Ben-Ari. His longtime foils The Roots stretch out beside him during the string-laden throwback jam “Hang On In There”; on the sparse, slow-burning “Overload”, he teams up with R&B polymath Miguel, whose wail beautifully complements Legend's rasp.
