“Nick Jonas Is On The Verge Of Something Awesome.” This was the headline when I reviewed the Jonas Brother’s self-titled solo album in 2014. My thought back then was that, buoyed by the falsetto-powered pop-R&B jam “Jealous,” Jonas was edging toward a truly fascinating career in pop music. In hindsight, I was extrapolating a lot from one endlessly listenable single — think of “Jealous” as a Muppet Babies version of Miguel’s “Adorn” — and trying to talk myself into the idea of Jonas as some kind of future pop auteur.
