Julien Temple explores the alternative side of the festival away from the spotlight of the main stages, where the event reconnects with its, shall we say, more radical and countercultural origins. Expect nude women straddling the large stones from the Stone Circle (note: they might not actually show that, but it does happen). Filmed in 2011, the documentary offers an insight into why people flock to experience the underground music and performance art of Glastonbury's lesser-trodden fields.
