The wide-ranging sounds that have inspired this pop chameleon are on display here. His murmured ballads have precursors in the artful restraint and melodic pathos of Joni Mitchell and Damien Rice; Bon Iver's gauzy indie pop reverberates in his muted strums. And Stevie Wonder's jazzy soul and Eminem's rhythmic bravado nod to the hip-hop and R&B cadences that colour so many Sheeran tracks.
