Does anyone know the artist of this music track?

I could have sworn this was on a kill bill movie, but from looking at the soundtracks of 1 and 2, it doesn't look like this song is listed. I would love to download this song / album, but I have no idea who sings it...

I don't have a complete cut of the song, just this snip:

Thanks!!

It is on the Kill Bill soundtrack (vol 1) track 9

its called Battle Without Honor or Humanity by Tomoyasu Hotei.
