One of the largest dance festivals in the UK is underway in Stratford-upon-Avon.
Global Gathering attracts thousands of electronic music fans each year and is taking place this weekend at the Long Marston Airfield.
The event is now in its twelfth year – launched in 2001 by the Birmingham nightclub Godskitchen.
The first festival in 2001 saw 25,000 revellers dance the day and night away.
Over the years the festival has grown in size – it has doubled in capacity – with 50,000 visitors and 30,000 campers now stay overnight to see two days of live acts and DJ's.
Organisers of this year's event say it has been challenging because of the impact of the Olympics.
There's a nationwide shortage of portable toilets and catering vans because of the Games.
– James Algate, Global Gathering Organiser
"This year we have seen a pull on resources and an increase in costs due to the Olympic factor with site facilities being the main items most difficult to come by...
"I am certainly glad we made the decision to stick to our historical date of the last weekend in July, even if it meant going up against the opening ceremony, as our ticket sales are on for a record year at the festival."
This year's headline acts include South London rapper Tinie Tempah, and Drum and Bass duo Chase & Status .
Warwickshire Police are using social media to give advice to festival goers attended the event.
The force will provide Twitter updates in case there are traffic delays or weather problems.
– Superintendent Martin Samuel, Warwickshire Police
“Twitter, and other social network sites, are proving to be an ideal way for the police to get important information to specific audiences quickly.
“As well as providing crime prevention advice and information about traffic management to the thousands of people attending Global Gathering, we will also be able to use it if, for example, there are any weather related issues which we need to tell people about quickly.“
With thousands of vehicles leaving the site on Sunday morning, motorists are being warned to avoid using certain roads because of expected traffic problems.
Non-festival road users are being advised to avoid the B4623 between Stratford and Mickleton, and to find alternative routes during the festival.
