JD McPherson Undivided Heart & Soul New West New West Records JD McPherson has long been one of the more inventive artists with deep blues roots, thanks to a strong, expressive voice suited to a variety of genres and songs that tamper with familiar templates in subtly intriguing ways. On the exhilarating Undivided Heart & Soul, McPherson makes this implied versatility explicit, expanding his sonic palette to exciting effect, from an eerie ballad (“Hunting for Sugar”) worthy of being repurposed as either a ‘50s teen lament or modern RnB, to sizzling rockabilly (“Bloodhound Rock”).
