These are some very beautifully recorded vocals, I love the voice and melody-very powerful yet peaceful at the same time.. This could be used in multiple styles- a classical epic piece after a battle with a lot of soldiers lives have been taken, and a calm is sung for their souls. This would even sound great put over a hip hop song every eight bars or so. some thick reverb and a slight delay would make this damn creepy.
there's not much to it so I can't give it a 10/10, but I think this is a near flawless sample...great stuff
