The Ghoul tells Rolling Stone: "We came up with this mixture where we could combine all our favourite adolescent music styles. We found a way of having an extreme metal riff then throwing a pop melody over it.

"After that it was, 'Oh, sh*t - maybe we could turn it into a horror-rock band, and we could throw in this very childish sort of fascination for horror films."

However, there's a deeper message behind their work, he says. "We're dabbling with mankind and his or her relationship to God. That's been the thing through all three records. It will be the thing on the fourth too."
