Since 1992, commissioning organisation Artangel has collaborated with practitioners in all areas of the visual and performing arts to produce unique installations and events in locations beyond the walls of the cinema, gallery, theatre and concert hall. It helped artist Rachel Whiteread cast a house inside-out in concrete in a Mile End Street; facilitated composer Orlando Gough and Alain Platel's promenade performance of 16 London choirs in Camden's Roundhouse and assisted artist Michael Landy to destroy everything he owned in Oxford Street's empty C&A store.
