Radio stations have started playing the lead single "Rats" off Ghost's upcoming album today. Can't provide a YT link which is staying up for a while because they are deleting everything quickly, but you'll find ways to hear it if you want. And it's fantastic IMO, catchy but also with a ton of interesting guitar work.
In terms of the imagery, they are apparently dropping the Papa Emeritus bloodline and go with Cardinal Copia instead. Probably not the final look, but he's been portrayed both in black and red robes so far. Pretty cool too that they had a red cardinal bird in the "Square Hammer" video (at about 3:27 below). Foreshadowing done right!
