With its huge hook and synth-layered pulse, the international club smash “Euphoria” is an ideal calling card for Heal, the widely anticipated debut full-length from Scandinavian Idol alumnus Loreen. Stacked with similarly sweeping singles (“Crying Out Your Name,” “In My Head”) the singer’s big-throated heartbreak stands in stark relief to the album's electrifying, hyper-modern production. During the rare moments when her tone is subdued (as on the austere ballad “Do We Even Matter” or the atmospheric closer, “Heal”) Loreen’s expressive gifts as a vocalist are on full display.
