The all-robot band Compressorhead makes those Chuck E. Cheese animatrons look like a bunch of clowns!

The 78-fingered guitarists are both playing their bolts off, but the four-armed, mohawked drummer robot with is programmed head-nodding steals the show right out from under them.

Compressorhead ("the world's heaviest metal band," according to their website) can be seen live in 2013 at Australia's 'Big Day Out' music festival.
