Metallica members James Hetfield and Kirk Hammett have lent their voices to a new cartoon.

The Cartoon Network series ‘Metalocalypse’ follows a Norwegian heavy metal band called Dethlok and the mayhem they get up to.

As well as the Metallica stars, members of Nevermore and Arch Enemy are also contributing their voices to the series.
