It's some yacht rock-style vocals that provide many of the album's most beautiful moments - Lighthouse wouldn't sound out of place on a Hall & Oates album (apart from the rap bits perhaps) and on One Time guest singer Phonte is channelling Toto. But it works.
Elsewhere, neo-soul singer Bilal Oliver does a serenading star turn on album highlight The Otherside, Kool On is, indeed, one of the coolest things to get down to this summer, and if the beat of Tip the Scale was any more laid-back it would need beating with a big stick. But even that works.
Then there are the delicate glitches and trumpet runs, and stunning fragility of a song like Sleep, which is an example of just how exquisite and accomplished this eleventh Roots album is.
Though the guest list is not as diverse as How I Got Over, experimental folkie Sufjan Stevens' brief but beautiful turn on the first part of the album-ending Redford Suite is an inspired choice. In fact, Stevens' song Redford (For Yia-Yia & Pappou) from his 2003 album Michigan is the inspiration for the concept album's main character Redford Stephens. The record details his life growing up, struggling to survive and turning to crime to make ends meet.
Not that it necessarily plays out like a concept album, because apart from the bookends of Dun at the beginning and the Redford Suite, the songs stand up by themselves.
Just like the Black Keys' latest, released last week, with undun the Roots make a late run for album of the year.
Stars: 4.5/5
Verdict: Another album of the year contender
