Complete and missing at the same time? Just as the title of this exhibition, taken from Beckett, includes a paradox, so too do the first few seconds in the gallery. You think they haven't finished the installation yet. The place stinks of paint and people are wandering around in overalls. But the object is, in fact, complete - and the show is filled with works that whisper a simultaneous absence.
The unfinished business is Nedko Solakov's A Life (Black and White), two walls endlessly being repainted in black, then white. Absurdist, futile and yet deeply involving, this is the painterly equivalent of the myth of Sisyphus. Joao Penalva's Mister shares Solakov's indebtedness to Beckett in its blending of the mischievous and the existentially terrifying. His film shows a shoe narrating its life story. There are echoes of Beckett's Not I, in which only a character's mouth is illuminated by spotlight, as the shoe explains how it lost the rest of the body to which it once belonged. The lunacy and horror of the story casually unfold in the darkness. The terror it suggests, the dissolution of self, is undercut by the fact that the speaking piece of footwear has something of Basil Brush about it.
But this is not just about high drama. Fiona Banner's Full Stops - punctuation marks from different typefaces, rendered in quirky 3D - sprawl silently, like giant chess-set pieces on the loose, and Mariele Neudecker transforms a deeply romantic image - the light-filled interior of a gothic church - into a tangible 3D reality, like a doll's house version of the scene. Simon Starling shows a broken, enigmatic narrative - a puddle of melted metal, once a ladder and now an unreachable crow's nest - while Eugenio Dittborn has painted by airmail. Four cartons, posted from Chile to Glasgow, reveal the journey they have made via postage stickers and notes.
Absence, presence and meaning hover in space between the works. There's the drama of silence, and the power of the absurd. The atmosphere here is totally Beckett, complete with evocatively playful missing parts.
