Good live metal vids

[WNxScythe]

I'm looking for something off youtube or the like that I can use for an intro to my "demonstrative" speech on metal... just something that's like 30 seconds long (obviously I can cut down a longer vid) that pretty much exemplifies everything that is metal (something really intense)

Suggestions?

How about 1:20 --> 1:50 of that one?
