Javiera Mena has evolved from her early days as an indie queen with a fondness for glittering electronics. Picking up from 2014's beats-forward Otra Era, the diva once again embraces idiosyncratic grooves aimed at quirky club kids on Espejo. There are emotion-drenched disco anthems ("Espejo") full of explosive breakdowns, and jittery electro-pop oddities ("Aire") that double as jubilant floor-fillers. But with a vibe that's simultaneously majestic and wistful, her ballads like "Alma" and "Todas Aquí" remain as uniquely affecting as ever, evoking '80s synth-pop at its most ravishing.
