‘How to shout YAHOO!’, the exhibition’s title piece, is a perfect example of how Kang’s work melds the sublime/eternal with the frivolous/instant. Set up in the first space of the gallery is a desk, flanked by shelves that support a beam, allowing two iPhones to hang on their chargers over a magazine. This is National Geographic, open on a fold-out photograph of a mountain range. A phone number is written in permanent marker on the wood next to it. An explanatory video playing nearby explains ‘how to shout yahoo’; I’ll summarise. Find a picture of a mountain, use one phone to call another and set both to speakerphone. Then, holding them at about 20cm from each other to ‘calibrate’ the phones, shout YAHOO! and the noise you make will be amplified by distortion and echo as it would atop a ‘real’ mountain.
There’s a really charming current of synaesthesia running through the whole show. Kang is interested in ‘cognitive errors’ – slips in processing made by our brains when responding to potentially misleading stimuli – and chooses to embrace and even engender these errors rather than avoid them. His artwork is not tromp l’oeil. Rather, the artifice of his experiential works is crucially laid bare, and it’s your brain that does the backflips.
