The falsetto in the beginning of the song? Oh yes it is actually Elnur himself. Impressive stuf. Vocally Elnur knows exactly how to play the Eurovision game as he's been here before.
I'm actually liking the aqua blue and red backdrop, but I'm agreeing with the majority that the dancers more or less ruin the way the performance is shown. Contemporary dancing for the sake of it, takes attention away from the song itself.
