Roger Hiorns is a busy boy. Ikon Gallery in Birmingham plans to host a survey of the UK artist’s work in December, and he is also due to present his first major off-site work with Ikon, which involves working with the choir of St Philip’s Cathedral in the city, on 15 and 17 June. “Rather than standing to sing in stalls behind the altar, the choristers will undertake choral evensong while lying on their backs on the floor,” says a spokeswoman for the project. Hiorns’s arrangement of the choir neatly plays with ideas of life, death and consciousness. “I am fascinated by putting a wedge between various established authorities; one of them is the church,” he says.
