Glastonbury Festival is the largest greenfield music and performing arts festival in the world and a template for all the festivals that have come after it. The difference is that Glastonbury has all the best aspects of being at a Festival in one astonishing bundle.
It's like going to another country, a hip and thrilling Brigadoon that appears every year or so. Coming to Glastonbury involves a fair amount of travel, and probably a queue to get in but, when you get past these impediments, you enter a huge tented city, a mini-state under canvas. British law still applies, but the rules of society are a bit different, a little bit freer. Everyone is here to have a wild time in their own way.
