Come and have a go in San Fransisco... if you think you're hard enough!

METALLICA are offering their fans the chance to play bass for the group for one night only.

According to their official website, the band will play at a party in their hometown of San Francisco to celebrate the launch of their new, improved website.

Fans who sign up for the official Metallica mailing list will be entered in a draw to decide who joins the band on stage.

The audience will be asked to judge whether the stand-in bassist is good enough to continue playing after the first song.

The website launch party takes place on July 29. The winner of the stand-in bassist competition will also get a guided tour of San Francisco and dinner with Metallica. For more details, click here.
