Brutal Ballet are a classical ballet company with a twist. Instead of doing pirouettes to Tchaikovsky they dance to heavy metal music.
Bridie Mayfield started experimenting with this genre in Australia, and has recently moved the company to the UK with a new cast of dancers.
Their first performance was at TitanCon, a science fiction and fantasy convention in Belfast, where they put on a Game of Thrones inspired piece.
Stars of the popular fantasy drama Eugene Simon and Kerry Ingrams were in the audience.
BBC News went behind the scenes at the rehearsals in London.
