Zakk Wylde will be going to prison - to sing for the inmates.
Prior to their set at London's High Voltage festival on July 24, the Black Label Society frontman will be performing a solo gig on July 22 at HMP Stocken in Stretton, Leicestershire, as part of their anti-violence and anti-bullying campaign.
He will then answer questions from around 60 inmates after the performance.
The one-off show was organised by prison guard Officer Kevin Oakes, who got in touch with the guitarist and asked him to do something for the inmates at his prison.
It's not the first time Zakk has sung in jail - his debut with Ozzy Osbourne, whom he went on to play with for more than two decades, also took place behind bars in 1987. He also played for prisoners at Singapore's Changi Prison last December.
