That's what's so special about Chester. He does not even scream the insane highpitched scream in Given Up falsetto. He is using his full voice all the way. It's amazing, cause his speaking pitch isn't very high. Same as for Marilyn Manson.
It's probably a song that's not on the new album. That's my guess at least. Maybe they will give it away soon. Like a christmas present. That would be awesome!
