Over the next couple of days 120,000 people will be making their way to a dairy farm in Somerset for the annual mud-bath that is Glastonbury.
As it ever was, the main talking point is the weather, with the heavens set to open on Friday, just in time for the official first day of the festival and the day's headliners Arcade Fire.
But sketchy phone coverage will be combated with the addition of a network of 4G-enabled fibreglass cows (really), which will make it a lot easier to breathlessly tweet pictures of the inevitable protest against bear hunting enthusiast James Hetfield when Metallica take to the Pyramid Stage on Saturday.
Beyond the weather and the headliners (the festival being closed by Kasabian on Sunday), these charts will give you a flavour of how the next five days will pan out, whether you're a Worthy Farm veteran setting up your tent or a festival first-timer stuck in traffic outside Stonehenge.
