Glastonbury Festival in Pilton
The largest greenfield music and performing arts festival in the world, held on Michael Eavis's Worthy Farm near Pilton, Somerset, since its first edition in 1970. That inaugural event drew around fifteen hundred people for one pound admission including free camping and milk, with Marc Bolan's Tyrannosaurus Rex headlining after the Kinks withdrew.
Glastonbury matters because it turned a farm festival into a cultural world where music, politics, theater and community keep renewing each other.
