Deadland Ritual, the new band featuring founding Black Sabbath bassist Geezer Butler, ex-Guns N' Roses drummer Matt Sorum, Billy Idol guitarist Steve Stevens and Apocalyptica singer Franky Perez, will perform several songs from Sabbath, Idol and Velvet Revolver on its upcoming tour.

Asked by Billboard how Deadland Ritual will fill out its live set when the group hits the road in late May, Butler said, “We're thinking about doing seven original songs, which we've done up to now, unless we write more between now and May. Probably three or four Sabbath songs . . . But more obscure Sabbath songs, rather than 'Iron Man' or 'Paranoid,” that's been done a million times.”

Butler added that they'll also play “a couple Velvet Revolver. 'Slither' definitely, I'm not sure bout the second one, and I think we're going to do 'Rebel Yell,' Billy Idol! (laughs) I have to learn them all between now and May.”

Butler found himself unemployed after Sabbath played the final shows of its 49-year career in February 2017. He told us at the time that the decision to make the tour Sabbath's last was not a difficult one: “I realized on the 13 tour that we couldn't do it for much longer, so the natural thing to do is to all agree on one last tour. Once we agreed on one last tour, that was it. We just set it up and we all agreed that there won't be any more Sabbath after this. It's like a natural progression kind of thing — natural end to the band.”

Butler said that there is no long-term plan for Deadland Ritual at the moment, remarking, “We're just going to see how it goes.” The band will make its U.S. live debut on May 28th at the Troubadour in West Hollywood, California. A European tour will follow in June.
