Of course it's not all about music; The Big Feastival 2015 will feature a number of celebrity chefs including Raymond Blanc, Monica Galetti, Jasmine and Melissa Hemsley (a.k.a. Hemsley + Hemsley), Ella Woodward of "Deliciously Ella" fame and, of course, Oliver himself. There's also a "Cheese Hub" hosted by Alex James for tasting his range of artisan cheeses, a "Little Dudes Den" for family fun, a funfair, lifestyle markets and lots of delicious food to try and buy.
The Big Feastival takes place at Alex James' farm in the Cotswolds from Aug. 28 to Aug. 30, 2015. Buy tickets here.
