In 2012, Campbell and the other members of Dio's first lineup (plus vocalist Andrew Freeman) formed a project called Last in Line to pay tribute to Dio.
"[What] we do in Last in Line, and what they do with the hologram, I think it's all mutually to each other's benefit," he says. "I think we're all perpetuating, we're all keeping the music alive, and that's a good thing.
"So I think if the hologram brings more attention to Last in Line, then that's good for Last in Line," he adds," if our playing the music brings more attention to the hologram, then that's good for them. So I think it's a win-win. I have no real strong opinion on it. Like I said, I've never seen it, so I can't say."
The show debuted at this past Wacken Open Air metal festival. It features recordings of Dio's live vocals with a live backing band. The show has announced tour dates in Asia, Australia, Europe and South America.
