On the 1st song (Part A: The Call) around the end of the 3rd minute there is (to be more precise at 3:45) a chant/song which is used as a sample. I am trying to identify it, but I cannot find some reliable source on the world wide web. 
  
Namely, we have the same pattern used in Macedonian Pop Song. 
 
 (It is on 01m:18s)  
Thanks! 
  
btw... Great album!
