I've been looking for possible music to play while gaming RT, and for now I found that MUSE "Black Holes and Revelations" album from 2006 is pretty good for this.
The music video of "Knights of Cydonia" is an insane collection of western + kung fu + future tech. And the title "Black Holes and Revelations" makes me think about chaos, the processional of the damned and similar.
Also trying out Smashing Pumpkins "Machina/ the machines of God", since it is kind of creepy here and there.
Post your RT music!
