Thousands of people have been descending on Henham Park near Southwold in Suffolk for the Latitude Festival.
The event, in its ninth year, kicks off tonight with headliner, Lily Allen. The singer stepped in at the last minute to cover sickness.
The weekend is a mixed bag of arts, comedy, music and according to the forecast, weather too.
Latitude attracts some big names - this year they've got Chrissie Hynde, Alison Moyet and locals like Emma Freud and her partner, Richard Curtis.
"We have dance, we have West End shows on the Waterfront stage, we have a huge kids' area which is a festival within a festival really. There's something for everyone. Kids come, babies come, even my granny is here. So everyone turns up"

Latitude have suggested alternative routes to avoid delays on the A12 at Yoxford following a serious collision earlier.
- If you are on the A12 stay on this route to travel to the festival site. There are diversions in place which will take you from Saxmundham via the B119 to Framlingham Castle where you can pick up the A1120 to Yoxford.
- If you are travelling from the direction of London, Essex or Ipswich please use the A14 towards Bury St Edmunds and then turn off on to the A143 to Beccles, from here you can follow festival signage.
A man's in a life threatening condition following a crash between a car and lorry at Yoxford in Suffolk this afternoon.
The driver of the car has been airlifted to Addenbrooke’s Hospital in Cambridge.
The lorry overturned into a nearby field, but the driver wasn't hurt.
Police have had to close a northbound stretch of the A12 at Yoxford, but the southbound carriageway is also being affected.
The closure is causing disruption for traffic heading to the Latitude Festival at Henham Park near Southwold.
Drivers are being told to avoid the area and the road is expected to be closed until at least 7pm.
Pop star Lily Allen will headline the opening night of the Latitude Festival in Suffolk after indie band Two Door Cinema Club pulled out of the event.
The decision comes after the band's singer, Alex Trimble, announced he was too ill to perform at the Henham Park arts and music festival.
Allen, whose latest album is entitled Sheezus, stepped in at the last minute to fill the slow.
The outspoken star sent her best wishes to the performer and said she was looking forward to taking to the stage at Henham Park.
She said: "So sorry to hear about Alex from Two Door Cinema Club. However I am more than happy to step in."
"I've never been to Latitude but I hear it's fabulous and I can't wait to get my heels on for some serious dancing action on Friday evening - so, so excited."
Two Door Cinema Club issued a statement, saying: "It is with a heavy heart that we are going to need to cancel our upcoming shows at Latitude and Bournemouth Academy.
"Alex collapsed at Seattle airport on the way to London and has been hospitalised with a chronic stomach complaint.
"We are devastated to have to cancel shows that we were so looking forward to. We can only apologise and hope for your understanding at this time."
Melvin Benn, managing director of Festival Republic which runs the event, said he was sad that Two Door Cinema Club had been forced to cancel their performance "under advice of doctors".
He added: "We wish Alex all the best and a speedy recovery.
"We are honoured that Lily Allen is able to step in at the last minute and would like to thank her for filling the headline slot.
"After her show-stopping performance at Glastonbury Lily was a natural choice, the Latitude audience are in for something really spectacular."
