Ibeyi is a derivation of the Yoruban word for twins, which Franco-Cubans Naomi and Lisa-Kaindé Diaz are. Their stunning 2015 debut mingled Afro-Cuban, Yoruban, European electro-soul, jazz, hip-hop, and classical, and the sisters’ harmonies invoked Santerían orishas while reflecting on heritage and family, including their late father, Buena Vista Social Club conguero Angá Diaz. On this year’s Ash, the blend is sleeker and trickier, with intricate vocal choruses punctuated by bata drums, sometimes edged with dissonance or elegantly spare. The songs address spiritual and emotional resolve to confront the evils of these Trumpian times with resilience, resistance, and retention of the high moral ground. “We Are deathless” is their response to racial profiling, while Kamasi Washington’s saxophone slinks about conspiratorially. “No Man Is Big Enough for My Arms” is woven around empowering excerpts from Michelle Obama speeches. And the solemn, riveting centerpiece, “Transmission/Michaelion,” offers strength and hope: “We sing and our tears dry.” Chicago R&B singer/producer theMIND (aka Zarif Wilder) opens.
