Turn Blue is the perfect title. We’re talking mood music for heads looking to soak their worries in waves of psychedelic soul (“Weight of Love”), Floydian space (“Bullet in the Brain”) and hazy disco balladry (“10 Lovers”). A lot of this delicious moodiness has to do with the fact that Turn Blue is a love album -- or, more accurately, an album about love lost. On the Beatles-inspired “In Our Prime” Dan Auerbach sounds utterly lonely and weary, someone for whom nostalgia is a prison. But on the upbeat “Gotta Get Away” he’s chiefly preoccupied with fleeing the hell of heartbreak.
