With their very melodic Antipope-rock, Gregorian Rock’n’Roll, their tours are continually sold out and they do a fun sort of marketing. Rumored to be a sort of all-star band, but since all the artists are Nameless Ghouls and the singer is just Papa Emeritus (I – III), it’s hard to know for sure.
In the US they are called Ghost B.C. for trademark reasons. And I think they’re even more popular there than in Europe.
