Jolly Joker has 1 DEF CON ONE concert.

DEF-CON-ONE are a metal band from Newcastle England. Def-Con-One was put together about ten years ago by Johnny and Antton who had played together in a previous band. From 1999 until 2009 Antton also played drums for black metal legends Venom. Finding any old musician to join would have been easy but finding people with the right attitude and drive was essential. Now that the band is complete we feel that the time is right to start showing the world what we do.
