Does anyone know where the sample at the very beginning/end of Pixillate comes from? (The Eastern singer)

Maybe something Paul Horn. I have no idea. Devin said he uses a lot of samples from his biggest influences in music.

Yes this is old, but I was just listening to it & it sounds to me like it's just Devy muttering & trying to make it sound like an eastern chant.
