Slipknot frontman Corey Taylor in his day job, scaring children and starting mosh pits.

And here is Corey off duty. He has fronted the band Stone Sour whilst unmasked as well as embarking on spoken word tours of the UK.

Black Veil Brides have taken the world by storm with their Motley Crue-esque looks and glam-metal anthems. As you can see, they're one of the most unique looking bands around.

However, lead singer Andy Biersack looks quite different when devoid of his kohl eyeliner and copious make up.

Marilyn Manson has shocked and awed for years now, he remains the ultimate wild rock 'n' roll star of recent years and puts in just as much effort to his appearance as he does his music.

Deadmau5 is dubstep's number one rodent and one of the most succesful DJs on the live scene.

Beneath the mask though, Deadmau5 is a tattooed man named Joel Thomas Zimmerman.

Kiss pretty much invented the idea of daubing yourself in make-up and pretending to be someone different.

When the black and white Kiss camouflage comes off Gene Simmons looks like this.

But here they are pre-robot head days looking Younger, Fresher, Smaller, Junior.

Joey Jordison is the masked drummer of Slipknot and Murderdolls guitarist.

And here he is unmasked and getting angry over a magazine. Rumours he inspired the look of the girl in The Ring remain unconfirmed.

Burial is spoken of in hushed tones and reverential love in dubstep circles but nobody knows what he looks like.

Or do they? This is William Bevan who many believe is the man behind the music.

Away from the hats and make-up this could be anyone down your local pub.

Add a bit of slap though and it is unmistakably Boy George.

This Swedish electro act rarely pose for photos without the aid of prosthetics, masks and anything else they can use to disguise their looks.

Two trunks later however and we have, The Knife!

Aaargh! It's Mortiis. He has been scaring us for years.
