Cosey Fanni Tutti (born Christine Carole Newby on 4 November 1951, in Hull, England) is best known as a performance artist and for her time in Throbbing Gristle and Chris & Cosey. Before both of these she was a performer with COUM Transmissions in 1969. Her addition changed the nature of the group which, when she joined, was still mostly a musical venture. From that point on, COUM performances became events or, in sixties parlance, happenings, involving props, costumes, dance, improvisation and street theatre.
