OK...I was listening to the radio in the car yesterday & Metalickadicka's song "One" came on. Not sure why, but I started to think about how much angrier (and sincere too) Hetfield's singing sounded back then...not so much specifically that song, but also in general in their earlier catalog. Then I got to thinking how much a metal singer's vocal delivery changes with age...more so after commercial/financial success. What used to sound like anger/angst in their voices, which is what initially drew in the fans, now sounds pussy in comparison. Obviously it must be harder to sound angry when you're living the good life, and I can understand that. Unfortunately, IMO, the songs usually suffer because of it, but oh well...that's why the young overtake the old. 
Anyway, this brings me to the question...who do you guys think is the oldest metal singer that still sounds sincerely angry/pissed in his vocal delivery? Not necessarily on every new song, but just somewhat consistently.
I really can't think of anyone 40+ except for maybe Tom Araya. Although even his vocals don't sound as sincere as they used to.
