Thoroughly enjoyed their live show at The Paladium back in March, I do find Papa Emeritus's comedy stylings most amusing though.
Friends of mine introduced me to Ghost before Download year before last (or possibly year before that), and I didn't get a chance to listen to them but really enjoyed their show. Had a good listen up before the Paladium gig and like you was impressed at the fusion of styles. Works so well, plus the multiple choral and instrumental layers make for a full and engaging listen.
