Rob Halford has revealed that he plans to collaborate with Ghost’s Tobias Forge.

Speaking to the Phoenix New Times, the Judas Priest singer said that he has discussed working with the Ghost frontman.

“I was in the dressing room with Tobias from Ghost, and we talked about collaborative opportunities. It’s fun for musicians to step into each other's world. It’s like different football teams — it’s the same game but a different play. I’m just very curious to see where my voice can fit in.”

Earlier this year Halford revealed that he has discussed working with former Emperor frontman Ihsahn in “a black metal project”, as well as Behemoth mastermind Nergal.

“[The Ihsahn collaboration] keeps being about to lift the launchpad, but it never quite gets anywhere,” Halford told Noisey. “I met Nergal from Behemoth recently, and I said, ‘You know I love your kind of music. I would love to kind of put my toe into the water and see what would happen.’”

Black Sabbath guitarist Tony Iommi recently said that he and Halford have spoken about joining forces. “We’ve talked about it for ages,” Iommi told Metal Hammer. “When the time’s right it would be nice to write a track or two, or whatever. I’d like to do that. It’s nice to work with people that you respect and like.”
