At about the 7:00 mark this song gets insanely beautiful. The first seven minutes is all about creating a mysterious atmosphere for song to evolve through. I love how eclectic Geinoh Yamashirogumi's music is. It's experimental, but never boring.
He's from America. He's named after a character from Appleseed, or from a Buddhist temple meaning Mother Earth, depending on which you prefer. So the word has religious meaning which is probably why it's the name of this piece.
