Heavy rockers Metallica are to perform their eponymous 1991 album in its entirety at a former Danish prison, where inmates included serial killers and mass murderers.
The group has announced its June (12) concert in Denmark will be staged at Statsfaengsel.
The 150-year-old prison was shut down in 2006 and now serves as an occasional entertainment venue.
It's not the first time Metallica have been behind bars for a big gig - the band performed for inmates at San Quentin State Prison in California in 2003.
