Over the years The Underworld has become the heart of the alternative music scene in England. Little is promoted about the history of the venue, although it dates back to the opening of pub above The Worlds End. The venue is itself owned by Glendola Leisure.

In 2007, influential Canadian musician Devin Townsend chose to tell the press of his departure from touring, and the break up of his bands Strapping Young Lad and The Devin Townsend Band during a press conference for his album Ziltoid The Omniscient at the Camden Underworld.
