Sooo many bands mentioned but there is only one King of the Scream, Chester Bennington of Linkin Park. His 15 second long scream in Given Up (look it up on Youtube) is some sort of record I think. I agree with the general concenus on here, it only works when it's real. Bands that do it all the time like BMTH, etc only do it because they can and it donesn't work. Bands that mix it up with screaming, singing, rhythem, feeling, etc are the best sort of music. Anyone that says it's shit and "just screaming", imagine how many times a lead singer has to scream per night while on tour, they then have to do that night after night and do it so they don't destory their voice box, it is a skill.
