Serpentine South has opened Change Ringing, the first UK institutional exhibition of Justin Caguiat's new and recent works. On view 8 October 2026 to 10 January 2027, it brings together painting, sculpture, printmaking, sound and film in an installation that treats the Kensington Gardens gallery as an active participant: Caguiat has exposed original brickwork and altered walls so the building frames the work rather than merely housing it. The paintings refuse to sit still. Working with thermochromic pigments on copper panels, the Tokyo-born artist produces surfaces that shift colour and disclose different forms as temperature and light change, so no two visits look quite the same. The works drift between abstraction and figuration, recalling frescoes and murals while resisting any fixed reading. In one new site-specific installation the copper panels are wired to small heating pads triggered by the bells elsewhere in the gallery — ring, and the paintings themselves warm and change. Those bells are the show's second engine. Caguiat has cast a series of bronze bells in the shapes of flowers and plant seeds, in sizes from intimate to monumental. A score by composer Lily Pickett takes its logic from English change ringing, the tradition of sounding bells in ever-shifting sequences; here pistons fire in sequential code so the bells play mechanically in a continuous loop. The gallery walls gather and amplify the chimes, and Caguiat invites visitors to hear the building as a listening instrument — a nod to the concrete acoustic mirrors once built along Britain's coastline and to Le Corbusier's idea of architecture as an acoustic receiver. The exhibition extends Zodiac Machine, the project Fundación Sandretto Re Rebaudengo staged across a Madrid church, market and public spaces earlier this year — itself indebted to Justo Gallego Martínez's hand-built Catedral de Justo. Curated by Hans Ulrich Obrist and Natalia Grabowska with Alexa Chow, the Serpentine edition turns a rarely used back room into a small cinema for a 16mm film, with silkscreen posters by Irma Boom. Entry is free with booked tickets; a Saturday Talk on 10 October offers a guided tour with curator Alexa Chow.
