In 2005, Danzig's tours to support the "Circle of Snakes" album and the Blackest of the Black Tour were highlighted by the special guest appearance of Misfits guitarist Doyle Wolfgang von Frankenstein. Doyle joined Danzig on stage for a 20-minute set of classic Misfits songs: "To do this right, I invited Doyle to join Danzig on stage at 'Blackest of the Black' for a special guest set. This is the first time we will be performing on stage together in 20 years. It's the closest thing to a Misfits reunion anyone is ever going to see."
