I tried one song from everyone, I offcourse tried your all-time favorite live performance Faile, I've seen the pumpkins before with the orchestra nice bombastic sound and performance.
I never heard of Steelheart Uchiha, they're an 80's band right?? Pretty impressive voice he got there, but no need to overexxagerate(???) about it there are a lot more singers out there with that kind of range(at least what I heard in the song). I mean a lot of guys back in the days had that amazing range style: King Diamond, Rob Halford etc.
Damn, Gamer I watched your dragonforce-vid those guitarists are sick F^#@$% the battle between them at the end had some real hard-hitting riffing in them at a freakish speed!
Some more vids for you guys:
Classic Suicidal Tendencies-clip, one of my all-time favorite clips
Suicidal
One of the best live-acts IMO:
Hatebreed mofo's!!! 
Please do not post tones of vids without checking other people's out and try commenting on them both positive and negative.
