The song of diva Plavalaguna, performed on the armenian version of "The Voice"

The movie-version was created digitally and was thought to be impossible to sing because the human vocal chord was thought to be unable to switch that fast between high-pitched and deep notes.

This girl did it.

(I also found a version on Youtube where an opera-singer sings this song, but there is a point that sounds exactly like the thought-to-be-impossible bars in the movie-version, down to the digital artifacts, and the camera cuts away from her face during these critical bars.)
