What could be cooler than watching Rob Zombie live in concert? how about watching Rob Zombie in concert covering Metallica? Not THAT is the definition of awesome!   http://youtu.be/hekhwWGdzys

Most band's wouldn't touch covering such a classic hit as Sandman but not only does Zombie pull it off, he NAILS it! While Zombie's voice isn't James Hetfield's, Zombie's vocals still lend itself very well to the cover.

Watch the footage above and let us know what is the best cover you've ever seen performed.
