Metallica are giving fans in London and Berlin a chance to see them for just £5/€10.
The September 15th gig at the O2 Arena in London coincides with the release of the rockers' ninth studio album, 'Death Magnetic'.
They'll also play a date at the O2 World arena in Berlin on September 12th - the first band to play the new venue.
"Because this is a celebration, tickets prices will be, shall we say, 'retro'," their statement read.
"Only ten Euros for Berlin, five pounds in London! And the best part is that all the proceeds from the sale of tickets will be donated to local charities."
See? They're nice boys, really...
