singing is fine, it could be polished a bit more for esc, and I hope it will be (he has almost 2 months to do that)
however, those screams (beggining and the middle) are recorded, so I'm guessing we won't hear them on esc?
unless he goes for live screaming which isn't that easy as it may seem
and finally, I hope that entire thing will sound better on esc cause on this video, his voice and playback music are too separated (it's hard to explain this in english
), the music isn't loud enough or something
