The band's original members consisted of vocalist Dani Filth, guitarist Paul Ryan, keyboardist Ben Ryan (Paul's brother), bassist John Pritchard and drummer Darren Gardner.  With this line-up, Cradle of Filth recorded a demo in 1992, titled "Invoking the Unclean".  Soon after, they recorded their second demo, "Orgiastic Pleasures Foul" with new guitarist Robin Eaglestone (aka Robin Graves) and new drummer Was Sarginson.  Robin left the band shortly afterwards, but following the departure of John Pritchard, Eaglestone returned to take his place as bassist.  Guitarist Paul Allender joined the band at the same time.  Following these changes, another demo was recorded, titled "Total Fucking Darkness" (released commercially in 2014, bolstered with rehearsal sessions and a surviving track from the abandoned "Goetia" album).
