Cradle of Filth are an English extreme metal band, formed in Suffolk in 1991. The band's musical style evolved from black metal to a cleaner and more "produced" amalgam of gothic metal, symphonic black metal, and other extreme metal styles, while their lyrical themes and imagery are heavily influenced by gothic literature, poetry, mythology and horror films. The band has broken free from its original niche by courting mainstream publicity (often to the chagrin of its early fanbase), and this increased accessibility has brought coverage by the likes of Kerrang! and MTV, frequent main stage appearances at major festivals such as Ozzfest, Download, and even the mainstream Sziget Festival, and in turn a more "commercial" image. They have sometimes been perceived as satanic by casual observers, although their outright lyrical references to satanism are few and far between, and use of satanic imagery has arguably always had more to do with literary allusion and the shock value than any seriously held beliefs.
