Identification Required - Song from Vol. 1

Could any of you please try and identify the title and artist performing the song heard on the scene where kiddo is examining Hanzo's weapon display up in his attic/room?

It is a soft, pure vocal melody sung in a foriegn language, not in english.
thanks in advance.

Why not try looking at the tracklisting on the back of the soundtrack?

It is not on the soundtrack.

nttn huh

Hasn't this been asked before? I think it's something from Lily Chou Chou, there is a piece used in that film that I noticed in Kill Bill. Look up that soundtrack.
