In the final weeks of this brilliant show, I went again to the Serpentine Gallery and asked myself: is this a new era of exhibitions?
Entering the gallery I am hit by a sense of bewilderment. There is nothing happening. The house lights are on and all I can hear is music from another room. A gallery assistant asks me if I need help – I decline, enjoying the confusion. She tells me that dog-walkers in Hyde Park often confuse the Serpentine for a public toilet. I smile politely and go in search of the sounds.
