Duuuuude yes, more people need to discover this band. Even if you're not a huge fan of their music, as said above, their shows are REALLY something else. Their whole image and spectacle truly elevates them especially their live performances. Even though there are other modern bands I'd admit are better, I'd still rather go see Ghost than anyone else just because of their pizazz and style. Plus, I adore the pulpy/poppy/prog-metal take on the antichrist/satanic clergy gimmick. It's delightful.
Also, Darkness in the Heart of my Love is just... one of the best songs of the past ten years. It kills me every time I listen to it.
