An A is a record that rarely flags for more than two or three tracks. Not every listener will feel what it’s trying to do, but anyone with ears will agree that it’s doing it.
An A- is the kind of garden-variety good record that is the great luxury of musical micromarketing and overproduction. Anyone open to its aesthetic will enjoy more than half its tracks.
A B+ is remarkable one way or another, yet also flirts with the humdrum or the half-assed.
