The Stranglers: Dartmoor Prison (1992)

In 1992, The Stranglers became the first rock band to perform at Dartmoor Prison. The concert took place on Friday, September 18th. The band used a £10,000 sound system that was won by a prison warder, according to the Daily Mirror. The event was part of a wider effort to use music as a rehabilitation tool for inmates, with the prison officer behind the competition entry also believing music could be a valuable aid.
