Astonishing Heavy Metal Cover Of The 'Doctor Who' Theme (VIDEO)

WATCH: The Ultimate Heavy Metal 'Doctor Who' Theme Cover
|

It turns out that the Doctor Who theme has been covered in a heavy metal way a number of times, but never has it ever been covered so heavily, so metallically, so wonderfully as it has been by YouTuber 331ERock here above.

His real name is Eric Calderone, but by and large he's known as 'the guy who does awesome heavy metal cover versions of nerdy songs'.

After all, in his time he's lent his guitar string-strumming skills to the Back To The Future theme, the Game Of Thrones theme and the Teenage Mutant Ninja Turtles theme.

But this time, he's really outdone himself, taking the beloved cult BBC sci-fi show and making its iconic music even more incredible than normal - as well as the latest Doctor's personal theme, I Am The Doctor - and in so doing, Mr. Calderone has become one of our uber-nerdy heroes. Simple as that, really.
