Witch Taint started as a joke fake band from the King of Metal, comedian Dave Hill and spawned the Black Metal Dialogues, wherein Dave tried to get his fake band signed and the e-mail exchange is now heavy metal lore. Dave transformed the dialogues into a hilarious two-person show and having seen the show a few times, it's resulted in quite a few laughs.
Now Dave is taking the show to Wacken. That's right, there will be multiple performances from Witch Taint during the biggest metal festival of the year. More info here.
