Before their entry onto the stage of the Lab in 2015, the Franco-Cuban twins Naomi and Lisa-Kaindé Diaz were struggling with stage fright. A moment later, relaxed before the Montreux public, the anxiety they had been feeling just vanished: enchanting and free, these Parisians fond of Kendrick Lamar and friends with Beyoncé sang as though they were possessed, serving up their melancholic, tender, and mystical soul steeped in the Yoruba culture and tinged with electronic sounds. We were swaying. Four years and two albums later, including the stupefying Ash (2017), our fascinated ears continue to listen to the perfect body of work sung in English and Spanish by this instinctive duo that has won acclaim from the cream of the English-speaking world. First among them: Pharrell Williams and Adele, unconditional fans.
