On her major-label debut, Shakira impressively injects Caribbean sounds with pop finesse and a big rock aesthetic. On the revealing “Estoy Aquí,” the Colombian singer announces her arrival, as her contralto floats atop a rapid-fire melodic hook. Elsewhere, the bossa-tinged “Antologia” is ripe with sincerity, while the groovy “Un Poco de Amor” takes inspiration from dancehall reggae. Throughout, her voice remains distinct and utterly compelling, whether on top of Afro-Latin rhythms (“Donde Estas Corazon”) or over a straight-up rock jam (“Vuelve”).
