Have you ever tried to sing along on songs like Lying From You, Points of Authority, No More Sorrow, or any of their other heavier songs? I have a high singing range compared to most people...but damn I cannot sing more than a song and a half at full volume before my voice is just gone. To do 20+ song set lists night after night the way he does is crazy. Oh yeah, and try to sing The Catalyst all the way through on Chester's parts. Impossible. I can get to the second half of the song ("lift me up / let me go") and I lose it. It's insane.
