what is the name of he song when the curtain opens 4 underwater trick ?

I have been looking for the title of that same track. I can't find it anywhere. It plays during the curtains in the final Torture Cell scene in the flick. It's the only track I actually liked a lot in the entire movie and I still can't locate it. I love that music too, but it's highly difficult locating it. Any help from anyone else is much appreciated.
