Nothing short of a victory ballad, “Deathless” marks an empowered and empowering return from Ibeyi. The French-Cuban twins who compose Ibeyi, Lisa-Kaindé and Naomi Díaz, enlist Kamasi Washington on the stunning track. Washington lends detailed saxophone parts that dazzle. Director Ed Morris spearheaded the music video, in which the sisters appear to emerge from one another repeatedly. It’s provocative but beautiful, matching the song succinctly. Ibeyi have a forthcoming album, Ash, out 29 September.
