One of Ghost's Nameless Ghouls - probably Papa Emeritus since he's the only member of the band now - revealed lineup changes are actually quite frequent in Ghost, telling Merkur (via Google Translate):
"The masks are usually misinterpreted. It's not about dressing up. It is about anonymity. [With anonymity,] one can make quite different music."
He continued: "This is actually a problem with this project. For many musicians, this is not satisfactory.
"That is why we had many changes - 10 by now [since the band was founded in 2008]. On the other hand, you can get out of your own artist role and look a little more objectively. You never see yourself as the others see you. And you always see only how you want to be. This is a problem for many."
Asked whether all the lineup changes had a major impact on Ghost's sound, the musician replied: "No, it's all fixed. In the end, Ghost is like a play. If you see 'Faust,' you do not expect the text to be changed."
Discussing his role in the band, the nameless one made it pretty clear he's the group's leader, saying: "I've created the whole project. I've been working for six years, composing, designing stage shows, giving interviews. I feel recognized. This is more difficult for others. [I'm behind] around 95 percent [of all things Ghost]."
Asked about future plans, the fella replied: "Ghost is clearly outlined. Personally, however, I would also like to play guitar in a band. Currently, however, this is difficult, because Ghost takes all my time. I'm like a CEO. [Laughs] When I started, of course, I did not think what might become of it."
