Ghost (the band) has been crazy interesting to follow.
Papa Emeritus 2 was very much so a religious hardliner with a perverse side. Like the sexualized Aleister Crowley figure. Creepily spiritual, lover of women, lonely old man, but somewhat 'conservative'. The music had more chanting hymn themes with him. Lots of Latin:
Il Padre
Il Filio
Et Lo Spiritus Malum
Omnis Caelestis
Delenda Est
Papa Emeritus 3 was a play on charismatic Christian leaders appealing to the younger audiences. He stopped wearing the clerical vestments and replaced them with stylish hair and jackets. Songs like "He Is" were a direct play on modern Christian hymns used by megachurches.
So I can only wonder if this next Ghost album, with Emeritus Zero being elderly, will go back to a lot of chanting, Latin, or maybe some kind of harder approach.
