Luhring Augustine, New York’s Looking Out exhibition of early works on paper and recent sculpture by Rachel Whiteread opens on 19 September. Whiteread is best known for casting the spaces inside and around objects. The resulting sculptures are remarkably faithful to their source moulds, but also uncannily foreign in that they represent an inverse of the original object and require a constant reorientation of perception.  Absence is made present, interior becomes exterior, and the invisible is rendered visible.
