As summer draws to a close, Jaega Wise heads to the Bannau Brycheiniog (Brecon Beacons) to learn what goes into feeding the thousands of fans gathered for the Green Man festival. Over the past 20 years or so, the food at music festivals has evolved from mostly burgers, chips and noodles, to an array of traders cooking foods from all over the world, sit-down banquets, and chefs on the line up.

So what has driven this change, and can it continue to thrive while the cost of everything involved in producing it has risen so much? What has the evolution of better festival food meant for sustainability? And what do you do if you don’t want to spend a fortune on food at a festival, but still want to eat well? Comedian George Egg has some answers.
