Video footage of the three-robot act COMPRESSORHEAD performing a cover version of the classic song "I Love Rock 'N' Roll" — written in 1975 by Alan Merrill and Jake Hooker of ARROWS and made famous by JOAN JETT & THE BLACKHEARTS in 1981 — at this year's Big Day Out festival in Australia can be seen below.

COMPRESSORHEAD, which hails from Germany and consists of guitarist Fingers, bassist Bones and drummer Stickboy, plays a selection of well-known covers.

"When Stickboy debuted at Big Day Out 2008, I knew that if he found the right musicians to work with the sky would be the limit," said Big Day Out producer Ken West. "Stickboy's solo performance is still the most viewed YouTube act performing that year including RAGE AGAINST THE MACHINE. Now with Fingers and Bones by his side, I believe the world debut of COMPRESSORHEAD at Big Day Out 2013 will be the highlight not to be missed."

COMPRESSORHEAD's mission statement:

"Did you ever wonder what Danny Carey would sound like if he had four arms?

"How about if Angus Young had 78 fingers? Imagine what Robert Trujillo would sound like if he was actually made of metal?

"Well, wonder no more, meatbags.

"COMPRESSORHEAD is the world's heaviest metal band.

"Stickboy, Fingers and Bones are guaranteed to shake and rattle the world of meatbag music.

"Stickboy was created to exacting specifications. Four arms, two legs, one head, no brain. he plays a Pearl 14-piece kit with double kick. Stickboy junior, the bastard child of an unknown mother, takes control of the hihat shuffle. Inception date: 2007.

"Fingers joined Stickboy in 2009 and brings 78 purpose-built fingers, enough to play the entire fret board and pluck.

"Bones is the highest-precision bass player in known existence, and the youngest member of the band. Inception date: 2012.

"Stand aside, meatbags. Oil is thicker than blood."
