Embankment
“In the past few years my work has become more formal. Ghost came from a very specific place, whereas the piece I made for Documenta last year was not cast directly from a particular place, but from the underside of secondhand floorboards. It was a more generalised, formal piece. Plaster is my most frequently used material, but I have experimented with rubber, mainly out of a need for flexibility.”
