It's tough to make orchestral score music sound unique without getting in the way of the visuals, but Marcin Przybyłowicz and Mikolai Stroinski do a great job of putting together interesting musical ideas that really compliments the art form. Aside from the harmonic and melodic aspects of the song (you know, the important stuff), you've got some cool orchestration going on here, with Tuvan throat singing as well as some reed instrument that I can't place (possibly a harmonica).
