David Draiman is the lead singer for a Heavy Metal band called Disturbed and has an exceptional voice with a lot of range. From smooth, almost angelic, to rip your face off .
This is NOT a Heavy Metal version of this song. It is his taking this song to a level that is hard to believe while staying true to the original music and tune. It is very tasteful.
There is no screaming, no electric guitars, he just takes a relatively mellow song and turns it into something powerful with his voice.
The guy owns it.
