Compared to Eminem’s remarkable but wearying Campaign Speech, the song Black America Again is rap’s outstanding call to arms of election month. There’s a comforting 90s feel to its parent album, with the return of Common’s producer, NoID, and several hat-tips to fellow vets such as Public Enemy and Tribe, but the lyrics are all America 2016. Although there’s no hit to rival the Selma soundtrack epic, Glory, and a reunion with its vocalist John Legend is the worst of furrowed-brow, gluten-free beat poetry, this is intelligent, impressive work, breaking down complex issues rhyme by rhyme. Common may still struggle to be heard outside the echo chamber, but perhaps it doesn’t matter when it’s this sumptuously upholstered.
