Cerith Wyn Evans' gloriously uncategorizable oeuvre has spanned installation works, sculptures, photography, film, text and a recent collaboration with industrial-music pioneers Throbbing Gristle. Preoccupations with language and perception generally lead the works, from an exhibition at Tate Britain in which a computer randomly selected lines from William Blake's poetry to be reflected off a disco ball in Morse code format to "Inverse, Perverse, Reverse," a large circular mirror that showed viewers' reflections upside down, referencing Lacan's mirror-stage theory of identity while throwing a wrench into the expected experience of representation. Evans has said he wants his work to function as a "catalyst or reservoir of possible meanings that, for the viewer, could unravel many discursive journeys." In this series of conversations, Hans Ulrich Obrist draws Evans on these and other themes.
