A sign warns visitors not to touch the artworks In Walead Beshty’s new exhibition “Open Source”. The artworks in question, assemblages of office equipment precariously attached to metal poles, are still barely working in their original technological métiers – a metaphor, perhaps, of the fleetingness of technology. Elsewhere in the gallery, TV screens are split in half and mounted on walls their innards still flickering as if on some heteromorphic life-support. In the main gallery, the artist’s large-format Contact Prints frame five large Copper L-Brackets sculptures reminiscent of hyper-minimalist sculpture. Beshty’s smaller copper works, standard industrial sheets mounted in grids on the wall, are collusively linked by either imprints of drug prescription labels or the fingerprints of their installers. The entire show feels strangely foreboding – as if Beshty wants us as a witness for both the physicality and the pathos of technology through its mangled history. At Petzel through June 17.
