Glastonbury Festival is a five-day music festival held annually in Pilton, Somerset, England on Michael Eavis's farm. It features popular music acts along with dance, comedy and other performances. With around 175,000 attendees, it requires extensive infrastructure and is the largest greenfield festival in the world. Most staff are volunteers, helping to raise money for charity. The festival has been held annually since 1981, except for occasional fallow years for the land and organizers.
