Ibeyi, the moniker of 19-year-old French-Cuban twin sisters Naomi and Lisa-Kainde Diaz, is pronounced ee-bey-ee. It roughly translates as "twins" from Yoruba, the West African language and culture that spread to Cuba in the 18th century that has the highest rate of twinning of any culture in the world (95-100 twins for ever 1,000 live births). In the minimal, black and white video for "Oya," the first track from Ibeyi's in-the-works XL Recordings debut, the Paris-bred sisters appear as spectral-like versions of themselves sitting in a tree; it's soundtracked by their otherworldly, genetically-linked harmonies and some traditional Yoruba percussion. It's a sparse and haunting visual for a sparse and haunting song.
