Now I've seen the video, the audio sounds like a studio track rather than the live musicians even though the video itself looks like a legit performance. Certainly the vocal is a bit processed, but it doesn't sound sufficiently artificial to make me think its been radically pitch shifted. There are certainly people out there who can hit those notes for real, and so this guy could well be on the level.
Does anyone know who it is and give us some background?
