They say that thirteen is ‘unlucky for some’. Superstitious airlines leave out seat 13. Superstitious hotels won’t have a room 13. It’s the number of the ‘death’ Tarot card; the number of witches in a coven, and a number now associated with murder and horror courtesy of the Friday 13th franchise. An apt number then, for spooky legends and pioneers of black metal Cradle of Filth, who are set to release their whopping thirteenth album.
