Kill Bill music question

I enjoyed the heck out of the movie, but I thought some of the music was just so-so. What I’m wondering is, what is the name of the song that they used in the trailers? The one that is being played as O-Ren enters the club with her soldiers?

Battle Without Honor Or Humanity.

By Japanese guitarist/occasional movie star Tomoyasu Hotei. There’s a thread on here about him with some useful info from Sublight, but I’m too lazy to look it up right now.

I though the movie’s music was great. I’d even call it one of the best parts…

The “Twisted Nerve” whistling.

And the Green Hornet theme… just awesome.
