Is he singing in Polish or something? I can't make out a single word of the chanting.

I think that Mariusz uses his voice as an instrument, although he may be chanting in Polish, I wouldn't be surprised if he wasn't actually saying anything, he just sings noises quite often, that's one of the reasons I love his vocals so much, he does this particularly well on the Indukti album.
