Or if you liek the soundtrack to RTW check out a band called "'Dead Can Dance"
it has Hans Zimmer and Lisa gerad in it. Hans Zimmer composed the Glatiator soundtrack and Lisa did the vocals. He has done many soundstracks.. i wouldnt be suprised if he has some kind of apperance of the Troy or kingdom of heaven soundtrack.. But yeah check out Dead can Dance. Great group with very deep ancient sounding music
