One of the Nameless Ghouls from the Swedish occult rock band GHOST has told Billboard that the group has started working on its follow-up to 2015’s “Meliora” album, with plans to hit the studio in earnest once it comes off the road.

“We haven’t really started the pre-production yet, but I am very far into the writing,” the Ghoul said. “I’m usually piling stuff up, and then by the time it comes to pre-production, that’s when you start going through it and see what you have. I think that we have a pretty good idea of what we’re doing next, but once we start recording I usually get very inspired and work a lot faster.”

GHOST‘s new EP, “Popestar”, sold 21,000 copies in the United States in its first week of release. The effort landed at position No. 1 on both Billboard’s Top Rock Albums and Hard Rock Albums charts.

Meanwhile, the new GHOST original song “Square Hammer”, which is featured on “Popestar”, entered multiple Billboard charts, including Hard Rock Digital Song Sales at No. 7 (3,000 downloads sold), No. 33 on the Mainstream Rock Songs airplay chart, No. 36 on Rock Digital Song Sales and No. 41 on Hot Rock Songs.

“Popestar” was released on September 16. The effort includes covers of songs from bands like ECHO & THE BUNNYMEN and EURYTHMICS along with “Square Hammer”.

“Popestar” was helmed by English producer Tom Dalgety, who has previously worked with ROYAL BLOOD and KILLING JOKE, among others.

GHOST kicked off the “Popestar” U.S. tour on September 16, with dates scheduled through November 12 in Brooklyn, New York.
