Deep-thinking South London rapper Loyle Carner bares his soul on his confessional, jazz-infused hip-hop debut, Yesterday’s Gone. On dramatic opener “The Isle of Arran,” he samples a rapturous choir and some funky guitar licks, using his soft-spoken flow to ponder the meaning of death. Elsewhere, “Ain’t Nothing Changed” finds the MC languidly reciting rhymes as if perched on a bar stool in a basement jazz club, chewing over the realities of financial debt while accompanied by bluesy saxophone and a boom-bap beat.
