New singer Papa Emeritus III and two of the Nameless Ghouls were on hand to play a four-song set that included "Jigolo Har Megiddo," "Ghuleh" and "Zombie Queen" from 2013's "Infestissumam", and the title track to their 2013 Dave Grohl-produced EP "If You Have Ghost."

Following the performance, Ghost reportedly hosted 2- hour meet and greet with fans at the store. The Unholy/Unplugged trek will sees the band hit four more US cities this week, including Los Angles, Phoenix, Baltimore and Brooklyn .
