Heartthrob is deeply wounded and most of it is sad. Its emotional palette is reds and pinks, raw and tender, skin scrubbed too fiercely. But for all its sadness, all its discussion of never-going-to-work relationships, it’s an incredibly hopeful album. Not optimistic, per se but determined, teeth-gritted and snarling. Hope’s necessary for that, even if it is in small and ragged quantity. And hope’s never really stronger than when it’s down to its last shreds.
