THe fall didn't kill him apparently. He killed himself later.
I enjoyed this concert very much. Just after the end of this concert Charles Haddon (the blond singer) jumped into the crowd, severely injuring one girl. The place he jumped into the crowd was also the place where a few guys did some acrobatics during the concert., so I figure he thought the guys would catch him. He should have jumped during the concert, not after they all left the stage. It is speculation if that incident triggered his suicide later that day.
