This is a band made up entirely of mechanical robots called Compressorhead and they are looking to redefine the term heavy metal. Watching Compressorhead tear through Motorhead's "Ace of Spades" might just be enough to bring hard rock back to the top of the charts. And as someone noticed in the YouTube comments, it is the little things that make this so enjoyable, like the bass player standing almost completely still, just like every human bass player in rock history.
