Candlemass recently announced their coming EP House Of Doom alongside the title track. The version of the title track you've heard is the 6-minute edit and not the full-on 10-minute version that will be present on the 10" vinyl version of the release.
Candlemass has now revealed via Instagram (and a very blurry picture) that the long version of the track will feature Ghost frontman Tobias Forge on guest vocals. You can hear the edited version of the track below and the EP will be out May 25.
That’s right! Papa Emeritus III is the special guest on the exclusive 9.5 minutes long version of the House of Doom soundtrack! #specialguest #papaemeritus #ghost #candlemass #houseofdoom #vinyl #doommetal
