They take many cues from Yoruba culture, which has a high incidence, and reverence for twins. Their music is rooted in Yoruba folk songs and even their name is taken from the Yoruba word for twins.
In their music are elements of soul and folk. There's a spirituality to their sound; it sounds a bit like it could be used to soundtrack some kind of ceremony. They've released one EP, Oya, and are working on a debut album.
