These are the excerpts from the cassette tape I found. The collection of Balkan Music, probably ones from either Bulgaria or Macedonia. (I am not sure about the copy right issue on putting up an excerpts of recording, so I shortened them.)
Amazing odd meter rhythm.
The mid section of this is so great. The shifted melody of the Shawms (Algaita?) makes the ensemble so waving.
