Glastonbury Festival (originally Pilton Pop, Blues & Folk Festival current formal title Glastonbury Festival of Contemporary Performing Arts) is a
five day music festival that takes place near Pilton, Somerset, England. In addition to contemporary music, the festival hosts dance, comedy,
theatre, circus, cabaret and other arts. It is organised by Michael Eavis on his own land, Worthy Farm in Pilton. Leading pop and rock artists have
headlined, alongside thousands of others appearing on smaller stages and performance areas. Films and albums recorded at Glastonbury have been
released, and the festival receives extensive television and newspaper coverage. Glastonbury is the largest greenfield festival in the world, and is
now attended by around 175,000 people  requiring extensive infrastructure in terms of security, transport, water and electricity supply. The
majority of staff are volunteers, helping the festival to raise millions of pounds for good causes.
Inspired by the ethos of the hippie,
counterculture, and free festival movements, the festival retains vestiges of these traditions, such as the Green Fields area, which includes the
Green Futures and Healing Field. After the 1970s, the festival took place almost every year and grew in size, with the number of attendees sometimes
being swollen by gate-crashers. Eavis hosted the first festival, then called Pilton Festival, after seeing an open air Led Zeppelin concert at the
1970 Bath Festival of Blues and Progressive Music fourteen people invested everything they had to build the stage.
The Festival has been held
intermittently from 1970 through 2013.
