Tino Sehgal is a difficult artist to pigeonhole, with much of his work falling somewhere between human sculpture and performance art. But even hardened art cynics frequently find themselves at least intrigued by Sehgal’s bizarre output. “What gets seasoned gallerygoers talking is not the form or content of Sehgal’s pieces but the discomfort of interaction with unusual living, breathing human behaviour. A bit like the weird thrill of speed-dating or arguing with a Jehovah’s Witness on the doorstep.”
