Three years after its Golden Lion win at the 2019 Venice Biennale, Sun & Sea arrived in London. The Lithuanian performance on climate change was brought to the British capital as a collaboration between We Are Lewisham Borough of Culture 2022, London’s International Festival of Theatre (LIFT) 2022, and the Serpentine Gallery’s Back to Earth programme on the climate emergency.  This multitude of producers from all corners of the London cultural sphere begged the question: “what exactly is it?”, as many people enquired when I mentioned my summer evening outing. In each context, it became a different art form. Was it a public community event for Lewisham council, a theatrical production for LIFT, or performance art for the Serpentine’s contemporary art audience? Perhaps the most successful description is an opera, the ‘total’ or ‘ultimate’ art form—a beach opera to be exact.
