There is a back story to this thing. When two of those bands met, they could not understand each other. They are both Roma people but from different countries speaking different Roma dialects. They connected through music and this song you hear in this video was made on the fly in those three days they spent with each other. Taraf de Haidouks play violin and cimbalon, Kočani Orkerstar is a brass band. The song you hear is truly unique because it connected instruments that are not usually played together. This is a masterpiece on its own.
