The Glastonbury Festival, which takes place this weekend, is unlike any other festival in the world.
Where else could you find the biggest pop, rock and rap stars rubbing shoulders with Brazilian bossa nova legends, Nobel peace prize winners, film directors, politicians, punk ballet dancers, Russian dissidents and a giant fire-breathing rave spider?
They are some of the 26 essential things to look and listen out for this year.
Rain has fallen on the Glastonbury Festival as fans enjoyed the first day of music on the main stages.
A heavy shower on Friday afternoon brought out the wellies, ponchos and umbrellas and created puddles on site.
Friday's acts include Florence and the Machine, Motorhead, Mark Ronson and an unconfirmed band, rumoured to be The Libertines, on the Pyramid Stage.
However, Professor Stephen Hawking is unlikely to attend the event for an appearance in the Kidz Field.
A spokesperson for the physicist told The Telegraph he had pulled out "for personal reasons"
