Worked like a charm up through the Fragile.
Seems like he had a lot of ideas and thoughts and anger to express.
And it avoided the ego clashing that destoys so many bands.
I don't htink it is his approach that has changed... I just think that when you make your name by producing angry music, eventually, as you grow up and mature, you tend to become more introspective, and just can't run on the raw emotions that they did when they were younger and the world was balck and white.
It is just hard to maintain being psissed off all the time. I think that is more the reason you see bands liek NIN and Metallica lose their edge...it has nothing to do with selling out, becuase they ar ebeing true to who they are NOW, instead of being like Slayer and trying to pretend that they are still pissed 18 year olds. (which tends to go from making truly angry music to looking like a cartoon version o fyourself.)
I can't think of one singel "Angry " musician that has truly kept that creative fire that their single minded self-righteous indignation coupled with simplistic world view allowed them to have in their youth. Not NIN, not Megadeth, not Metallica, and definitely not Slayer.
Lets face it...getting old kinda sucks, cause you just don't have the energy, or the fanatical fervor you once had.
