Heavy rockers Metallica are calling on fans to help create the band's set lists for their tour of Europe next year (14).

The tracks the group performs at the Metallica By Request shows will be voted for by concertgoers.

Drummer Lars Ulrich says, "We are once again psyched to break free of the four walls in the studio to get energised by our devoted European friends for a couple of weeks next May and June.

"On top of that, the fact that all our nutty fans will pick the songs we play should be some next level fun and take a big load off my shoulders as the guy who usually writes the set list!"

The first announced festival shows will take place in Germany in June (14) with additional dates to be announced next week (beg02Dec13).
