They went viral a couple of months ago with their cover of "Ace of Spades"....

Now they won't stop.

"Compressorhead" is a robot band built in Berlin and are now on a small tour.

Cool idea actually! 

I wouldn't mind watching this robot band play a couple of songs at a festival or as an opener.

They've opened up their set list since "Ace of Spades".

Check em out!
