AX7 is awesome live, FFDP Kicks Ass as well..
Steel Panther's Death to all but Metal/Community Property are funny as hell. I would post Community Property Video, but I'm sure I would get the ban hammer.. Look for the explicit video if you dare..
As far as Nickleback goes, they tear it up live. My wife is a big fan, so I took her to a show, and I was in awe, those guys give you your money's worth.
I miss White Zombie, yes, I know Rob Zombie is still kicking it, but White Zombie is where it's at IMO!!
