Metal Evolution: EXTREME METAL?

http://www.indiegogo.com/ExtremeMetal

Their goal of $175,000 may be a stretch. Although, it does say:

"In the event that we don't reach our goal, we've brought together a consortium of Extreme Metal record labels and sponsors who have committed to helping make-up the funding shortfall."

I'd like to see it, however, if it is the length of the other episodes (45 minutes), trying to cram all the Extreme Metal styles into that short a time seems like inevitably, they will miss many names. However, beggars can't be choosers I suppose.

I do find it rather lame how it was *too extreme* for VH1 Classic to air, lol. Based on what? the lyrics? And this is on a Cable network, lol.
